11 OPERATION MP13 employs a smar inducor-less regulaor design o supply a regulaed DC volage from an AC inpu. A unique (paen pending) charge algorihm ransfers charge from he AC line when he line volage is below 32V o he capacior (C1 in he ypical applicaion diagram). The capacior is used as he charge reservoir for an inernal LDO o regulae VOUT. There are wo disinc modes of normal operaion; sarup and seady sae. Sarup A sar up, all pins are a zero vols, and he AC line supplies power o VIN hrough he recifier. An inernal 19mA curren source is enabled beween VIN and DR. This curren drives he base of an exernal bipolar ransisor which charges he capacior. This inernal curren source is only enabled when VIN is wihin is charging window, ypically below 32V. This charging echnique minimizes power loss during sar up. During his sar up condiion, <15.25V, he oupu regulaor is disabled. As long as < 15.25V, DR provides 19mA during is charging window which limis he oupu curren if is shored. When >15.25V, he oupu regulaor is enabled, and MP13 eners is seady sae mode. IDR IDR STARTUP =19mA UVLO IDR=2mA THOUT Figure 2: Base Curren vs. Volage Seady sae In seady sae mode, DR curren is increased o 2mA. Figure 2 depics he relaionship of he DR/base curren o volage. I is enabled during is charging window of VIN< 32V. This echnique adapively replenishes he capacior charge which supplies power o he LDO. This enables good efficiency. An inernal comparaor will limi he volage. These are he peak hresholds lised in he elecrical able. This furher improves efficiency by opimally limiing he drop ou volage depending on VOUT. If falls below 7.6V, he regulaor will be disabled, urning off he power supply. The EMI performance is enhanced by urning on and off he curren source a a conrolled rae. The following secions describe in much more deail he seady sae operaion. Figure 3 depics he seady sae waveforms for beer undersanding. VIN IDR IIN v v2 VIN THS v3 4 5 Figure 3: Seady Sae Waveform [1, 2]: A he ime of 1, he volage of and VIN is equal, hen VIN is rising higher han, so here will be some charge curren flowing ino capacior; A he ime of 2, VIN reaches he slow urn-off hreshold, he inpu curren increased o is maximum value; [2, 3]: To benefi he EMI performance, MP13 will urn on and urn off he exernal BJT slowly wih cerain rae. A he ime of 2, he driver reduces he driver curren slowly o urn off he exernal BJT, a he ime of 3, he exernal BJT is oally urned off; [3, 4]: During his period, he VIN is higher han he slow urn-off hreshold, he driver is urned off and no curren flowing ino capacior, he capacior provides he power o LDO for oupu load, a he ime of 4, he volage of drops from v2 o v3; 6 v4 MP13 Rev

A he ime of 6, VIN falls o he value equal o volage, here is no curren flowing ino capacior; [6, 1]: During his period, alhough he driver is acive, since VIN is lower han volage, so here is no charging curren, he capacior provide he power for he oupu load and he volage drop from v4 o v1 a he ime of 1; Adapive Acive Charging Window To minimize he power loss of BJT and LDO, MP13 inegraes an adapive acive charging window conrol, which mainain he maximum volage difference beween and VOUT say a a consan level, hus he peak volage is limied relaed o VOUT. When VIN varies from high o low volage ino is charging window and he volage is lower han PKLMT minus PKLMT _HS, hen he driver will be urned on and capacior will be charged up. If volage is charged up o is peak limi PKLMT which is relaed wih he oupu volage, hen he driver will be slowly urned off alhough VIN doesn reach is slow urn-off hreshold. Figure 4 depics he siuaion ha reaches is peak limi when VIN is in is charging window. VIN VIN THS PKLMT PKLMT_HS Acive Bleeder Circui Due o he parasiic capacior of VIN o GND, he inpu volage may no fall ino is charging window during normal operaion. A sar up, he acive bleeder is always on o pull down he inpu volage ino is charging window o charge capacior o is oupu enable hreshold THOUT a which momen he LDO is enabled. During seady sae mode, o guaranee he oupu ge enough energy from inpu pors, acive bleeder circui is enabled whenever he volage falls below BLDON. Besides, when he power supply is shu down, acive bleeder circui discharges he energy sored in parasiic capacior o ensure he circui can resar easily. Shor Circui Proecion The oupu curren is limied o 17mA (IOUT LMT ) if he oupu is shored o ground, which also decreases he volage. When drops below 7.6V ( UVLO ), he LDO urns off. The inpu volage hen gradually charges up o 15.25V ( THOUT ) o enable he LDO. When LDO urns on, he oupu curren drops he volage o 7.6V again. This process will coninue unil he oupu shor condiion ceases. Over Load Proecion The and VOUT volages will drop simulaneously if he oupu curren exceeds is normal value. When he volage falls o 7.6V ( UVLO ), he second sage LDO shus down immediaely. Then he inpu volage charges o 15.25V ( THOUT ) o enable he LDO. Due o he oupu curren limi circui, he maximum curren is limied o 17mA (IOUT LMT ) ypically. Shor o GND Proecion When is shored o GND, he driver curren will be reduced o 19mA (IDR STARTUP ) ypically o decrease he power consumpion of exernal BJT, hus he hermal damage of exernal BJT is prevened.

13 ambien emperaure sensing and proecion. The value of he NTC resisor becomes lower when he ambien emperaure rises. Wih he fixed inernal curren 8uA flowing hrough he resisors, he volage of RT pin becomes lower a high emperaure. When VRT is lower han VRT THL ( ypically.8v ), hen inernal OTP circui will be riggered and he BJT driver and LDO will be shu down immediaely. When VRT is higher han VRT THL plus VRT TH _ HS, hen MP13 will resar. Thermal Shudown Proecion Accurae emperaure proecion prevens he chip from operaing a exceedingly high emperaures. When he silicon die emperaure exceeds 16 o C, he whole chip shus down. When he emperaure falls below is lower hreshold of 14 o C, he chip is enabled again. MP13 Rev

14 APPLICATION INFROMATION COMPONENT SELECTION Seing he Oupu Volage The oupu volage is se o 12V by inernal large feedback resisors. Typically, he inernal upper and lower feedback resisor is 1.125MΩ and 125kΩ respecively. Adjus VOUT by choosing appropriae exernal feedback resisors. The recommended oupu volage is beween 1.5V and 15V. Defining he upper and lower feedback resisors as R UP and R LW respecively (refer o he picure in Typical Applicaion secion): VOUT RUP = R LW ( 1) For he exernal resisors o dominae over he inernal resisors, selec relaively small values of R UP and R LW compared o he inernal resisors. However, o minimize he load consumpion, avoid very small exernal resisors. For mos applicaions, choose R LW =1.2kΩ. To accuraely se he oupu volage, selec R UP ha can couner he inernal upper-feedback resisor value of 1.125MΩ ypically. The able below liss ypical resisor values for differen oupu volages. Table 1: Resisors Selecing vs. Oupu Volage Seing VOUT (V) R UP (kω) R LW (kω) (1%) 1.2 (1%) (1%) 1.2 (1%) (1%) 1.2 (1%) (1%) 1.2 (1%) Selecion of Capacior The bypass capacior on he pin needs o be sufficienly large o suppor sufficien energy. Calculae he capaciance (in μf) based on he following equaion: I τ C = OUT s Vripple Where, I OUT is he oupu curren (ma); τ s is based on he ype of inpu recifier for example, τ is 2ms for a half-wave recifier, and 1ms for s a full-bridge recifier, V ripple is he volage ripple on he capacior normally he ripple is limied o 2V o 3V. For bes resuls, use a small ceramic capacior and a large aluminum capacior in parallel. Oupu Power Capabiliy The following facors influence he MP13 s maximum oupu power: he inpu recifier (full bridge or half-wave); he capacior conneced beween and GND; he DC curren gain and collecor curren of exernal BJT; he oupu volage and he emperaure-rise requiremen of key componens, which is relevan o differen applicaion environmens.

15 EMI To mee he relevan conduced emissions sandard, slowly rise and fall he driver curren is adoped o urn on and urn off he exernal BJT. Using his conrol mehod, a smaller X cap conneced beween he inpu pors will pass EMI wih enough margins. Besides, a capacior conneced beween DR and will furher slow down he swiching process of exernal BJT for beer EMI performance. The larger value his capacior used, he slower swiching process and beer EMI performance will be go, however, he more power losses will be inroduced by his capacior and he longer sarup process will be, so i is a compromise o selec he value of he capacior conneced. Generally, wih a 1nF X cap conneced o pass EMI, a 2.2uF ceramic capacior for 12V oupu and 4.7uF ceramic capacior for 5V oupu is a good candidae o ge good compromise. Surge From is working principle, MP13 is working jus when VIN falls ino is charging window, so when surges happen a his momen, hen a lo of energy will be absorbed by BJT and MP13 due o he slow urn off process. To proec hem from damage, a fas urn off hreshold (ypically i is 71V) of VIN is se specially o shu down driver curren quickly. Since here is no bulk capacior o absorb AC line ransiens, MOV should be used o proec he IC o survive he surge es. Besides he value of fuse resisor will also affec he surge resul, he larger value used, he beer o faciliae o pass he surge es, bu he more power consumpion will be caused, in he meanwhile, he larger value of fuse resisor used, he easier o rigger is fas urn off hreshold, so 1~2 Ω fuse resisor is recommended in real applicaion. To pass 1kV surge es, 75V exernal BJT is recommended considering some margin, MP13 can pass 1kV surge es wih an appropriae MOV such as TVR1431 conneced beween he line inpu pors. Besides, he hermal pad mus be conneced o he GND for beer surge performance. PCB Layou Guide PCB layou is very imporan o achieve good regulaion, ripple rejecion, ransien response and hermal performance. I is highly recommended o duplicae E layou for opimum performance. If change is necessary, please follow hese guidelines and ake figure 6 for reference. 1) Keep he race from posiive oupu recifier o VIN as shor and wide as possible. 2) Minimize he loop area formed by posiive oupu of recifier, emier of exernal BJT and GND. 3) Minimize he loop area formed by VIN, collecor of BJT, emier of BJT. 4) Ensure all feedback connecions are shor and direc. Place he feedback resisors and compensaion componens as close o he chip as possible. 5) Place he NTC resisor as close o exernal BJT as possible for emperaure deecion and effecive proecion. 6) Oupu capacior should be pu close o he oupu erminal. 7) Connec he exposed pad wih GND o a large copper area o improve hermal performance and long-erm reliabiliy.
