8 Applicaion Informaion Operaion Overview The is an excellen primary side feedback conroller wih Quasi-Resonan operaion o provide high efficiency. The removes he need for secondary feedback circuis while achieving excellen line and load regulaion. I mees he green-power requiremen and is inended for he use in hose modern swiching power suppliers and linear adapors ha demand higher power efficiency and power-saving. I inegraes wih more funcions o reduce he exernal componens couns and he size. Major feaures are described as below. Under Volage Lockou (UVLO) An UVLO comparaor is implemened in i o deec he volage across VCC pin. I would assure he supply volage enough o urn on he and furher o drive he power MO. As shown in Fig. 11, a hyseresis is buil in o preven shudown from volage dip during sarup. arup Curren and arup Circui The ypical sarup circui o generae VCC of he is shown in Fig. 12. A sarup ransien, he VCC is below he UVLO(on) hreshold, so here s no pulse delivered ou from o drive he power MO. Therefore, he curren hrough R1 will be used o charge he capacior C1. Unil he VCC is fully charged o deliver he drive-ou signal, he auxiliary winding of he ransformer will provide supply curren. Lower sarup curren requiremen on he PWM conroller will help o increase he value of R1 and hen reduce he power consumpion on R1. By using CMO process and some unique circui design, he requires only 1.9A max o sar up. Higher resisance of R1 will spend much more ime o sar up. The user is recommended o selec proper value of R1 and C1 o opimize he power consumpion and sarup ime.

9 Principle of CV Operaion V IN In he DCM flyback converer, i can sense he oupu Np Ns volage from auxiliary winding. samples he auxiliary winding on he primary-side o regulae he Na oupu volage, as shown in he Fig. 13. The volage induced in he auxiliary winding is a reflecion of he secondary winding volage while he MO is in off sae. Via a resisor divider conneced beween he auxiliary winding and pin, he auxiliary volage is sampled afer he sample delay ime which is defined as 30~50% of Ra Rb V REF + - /H COMP Driver secondary curren discharge ime from previous cycle. And will be hold unil he nex sampling period. The Fig. 13 sampled volage is compared wih an inernal reference V REF (1.0V) and he error will be amplified. The error amplifier oupu COMP reflecs he load condiion and V D The overshoo here is minor conrols he duy cycle o regulae he oupu volage, hus consan oupu volage can be achieved. The oupu volage is given as: V Ra Ns 1.0V (1 )( ) Rb Na V F V D Fig.14 Where V F indicaes he drop volage of he oupu diode, Ra and Rb are op and boom feedback resisor value, Ns and Na are he urns of ransformer secondary and auxiliary. The undershoo would make he sample error. In case ha he oupu volage is sensed hrough he auxiliary winding; he leakage inducance will induce ringing o affec oupu regulaion. To opimize he collecor volage clamp circui will minimize he high frequency ringing and achieve he bes regulaion. Fig. 14 VIN Na Fig.15 R Np Ns shows he desired collecor volage waveform in compare o hose wih large undershoo due o leakage inducance induced ring (Fig. 15). The ringing may make he sample error and cause poor performance for oupu volage Ra COMP regulaion. A proper selecion for resisor R, in series Rb wih he clamp diode, may reduce any large undershoo, as shown in Fig. 16. Fig.16 -D-01 Augus

10 Load Regulaion Compensaion is implemened wih load regulaion compensaion o compensae he cable volage drop and o achieve a beer volage regulaion. The offse volage across is produced by he inernal sink curren source during he sampling period. The inernal sink curren source is proporional o he value of V COMP o compensae he cable loss as shown in Fig. 17. o, he offse volage will decrease as he V COMP decreases from full-load o no-load. I is programmable by adjusing he resisance of he volage divider o compensae he drop for cable lines used in various condiions. The equaion of inernal sink curren is shown as: I Load_COMP (V COMP 0.45) 9.75( A) The compensaion curren versus V COMP is shown as: 20 I Load_COMP (ma ) Fig. 17 Quasi-Resonan Mode Deecion V COMP (V) The employs quasi-resonan (QR) swiching scheme o swich in valley-mode eiher in CV or CC operaion. This will grealy reduce he swiching loss and he raio dv/d in he enire operaing range for he power supply. Fig. 18 shows he ypical QR deecion block. The QR deecion block will deec auxiliary winding signal o drive MO as pin volage drops o 0.15V. The QR comparaor will no acivae if pin volage remains above 0.2V.

If he sysem AC inpu is in low line, he will urn on in firs valley. If in high line, he swiching frequency will increase ill over he limi of 75 khz and skip he firs valley o urn on in 2 nd, 3 rd.valley. The swiching frequency would vary depending on he line volage and he load condiions when he sysem is operaed in QR mode. A medium or ligh load condiions (0.7V<V COMP<1.2V), he frequency clamp is reduced o 25 khz maximum. However, he characerisic in valley swiching behaves well wihou problem in his condiion. The will urn on in 4 h, 5 h. valley. Tha is, when he load decreases, he sysem will auomaically skip some valleys and he swiching frequency is herefore reduced. A smooh frequency fold-back and high power efficiency are hen achieved. A zero load or very ligh load condiions (V COMP<0.3V), he sysem operaes in minimum frequency for power saving. The sysem modulaes he frequency according o he load and V COMP condiions. R Q -D-01 Augus

As shown in Fig. 20, he deecs he primary MO curren from he pin, which is no only for he peak curren mode conrol bu also for he pulse-by-pulse curren limi. The maximum volage hreshold of he curren sensing pin is se a 0.8V. From above, he MO peak curren can be obained from below.

To compensae i, an offse volage is added o he R signal by an inernal curren source (I CC) and an exernal resisor (R 1) in series beween he sense resisor (Rs) and he pin, By selecing a proper value of he resisor in series wih he pin, he amoun of compensaion can be adjused.
