A stable pwer supply with an utput current f 600 ma requires nly tw capacitrs cnnected externally. Operating vltage range is frm 2.0 V t 6.0 V (1.8 V ~ 6.0 V fr IXD920xG versin). Output vltage is internally set in a range frm 0.8 V t 4.0 V in 0.05 V increments. The device perates at 3.0 MHz switching frequency, and includes 0.42 Ω P- channel switching transistr and 0.52 Ω N-channel transistr fr synchrnus rectificatin. The IXD9205 series perate in PWM mde, while IXD9206 series autmatically switching between PWM/PFM mdes.

(See the blck diagrams abve.) The Errr Amplifier cmpares utput vltage divided by internal resistrs R 1 /R 2 with the internal reference vltage. Amplified difference between these tw signals applies t the ne input f the PWM Cmparatr, while ramp vltage frm the Ramp Wave Generatr applies t the secnd input. Resulting PWM pulse determines switching transistr ON time. It ges thrugh the Buffer and it appears at the gate f the internal P-channel switching transistr. This cntinuus prcess stabilizes utput vltage IXYS Crp. 4 Dc. N. IXD9205_DS, Rev. N0 Characteristics subject t change withut ntice

5 The Current Feedback circuit mnitrs current f the P-channel transistr at each switching cycle, and mdulates utput signal frm the Errr Amplifier t prvide additinal feedback. This guarantees a stable cnverter peratin even with lw ESR ceramic lad capacitr. Reference Vltage Surce The Reference Vltage Surce prvides the reference vltage t ensure stable utput vltage f the DC/DC cnverter. Ramp Wave Generatr The Ramp Wave Generatr prduces ramp wavefrm signal needed fr PWM peratin, and signals t synchrnize all the internal circuits. It perates at internally fixed 1.2 MHz r 3.0 MHz frequency. Errr Amplifier The Errr Amplifier mnitrs utput vltage thrugh resistive divider cnnected t V OUT (FB) pin. If utput vltage falls belw preset value and Errr Amplifier s input signal becmes less than internal reference vltage, the Errr Amplifier/s utput signal increases. That results in wider PWM pulse and respectively lnger ON time fr switching transistr t increase utput vltage. The gain and frequency characteristics f the errr amplifier utput are fixed internally t ptimize IC perfrmance. Current Limiter The Current Limiter circuit mnitrs current flwing thrugh the P-channel transistr cnnected t the Lx pin, and cmbines functin f the current limit and peratin suspensin. When transistr s current is greater than a specified level, the Current Limiter turns ff P-channel transistr immediately. After that, the Current Limiter turns ff t, returning t mnitring mde. The driver transistr turns n at the next cycle, but the Current Limiter will turn it ff immediately, if an ver- current exists. When the ver current state is eliminated, the IC resumes its nrmal peratin. The IC waits fr end f the ver current state repeating abve steps (t1 n figure belw). If an ver-current state cntinues fr a few ms with IC repeatedly perfrming abve steps, the Current Limiter latches the P-channel transistr in OFF state, and IC suspends peratins (t2 n figure belw). T restart IC peratin after this cnditin, either CE pin shuld be tggled H L H, r V IN pin vltage shuld be set belw UVLO t resume peratins frm sft start. The suspensin mde is nt a standby mde. In the suspensin mde, pulse utput is suspended; hwever, internal circuitries remain in peratin mde cnsuming pwer. Shrt- Prtectin The shrt-circuit prtectin mnitrs the R FB1 /R FB2 divider vltage (FB pint in the blck diagram). If utput is accidentally shrted t the grund, FB vltage starts falling. When this vltage becmes less than half f the reference vltage (V REF ) and P-channel switching transistr s current is mre than the I LIM threshld, the Shrt- Prtectin turns ff and latches quickly the P-channel transistr IXYS Crp. 5 Dc.

6 At D/E/F/G series, Shrt Prtectin starts nce FB vltage becmes less than 0.25 f reference vltage (V REF ), disregard t transistr s current. T restart IC peratin after this cnditin, either EN pin shuld be tggled H L H, r V IN pin vltage shuld be set belw UVLO t resume peratins frm sft start. The sharp lad transients creating a vltage drp at the V OUT, prpagate t the FB pint thrugh C FB, that may result in Shrt prtectin perating at vltages higher than 1/2 V REF vltage. UVLO When the V IN pin vltage becmes 1.4V r lwer, the P-channel transistr is frced OFF t prevent false pulse utput caused by unstable peratin f the internal circuitry. When the V IN pin vltage becmes 1.8 V r higher, switching peratins resume with the sft start. The sft start functin perates even when the V IN vltage falls belw the UVLO threshld fr a very shrt time. The UVLO circuit des nt cause a cmplete shutdwn f the IC, but causes pulse utput t be suspended; therefre, the internal circuitry remains in peratin. PFM Switch Current In PFM mde, the IC keeps the P-channel transistr n until inductr current reaches a specified level (I PFM ). P-channel transistr s ON time is equal t ON = L I PFM / (V IN - V OUT ), µs, where L is an inductance in µh, and I PFM is a current limit in A. PFM Duty Limit In PFM mde, P-channel ON time maximum (t PON_MAX ) is set t 2D MAX, i.e. tw perids f the switching frequency. Therefre, under cnditins, when the ON time increases (i.e. step-dwn rati is small), it is pssible that P-channel transistr t be turned ff, even when inductr current des nt reach t I PFM. (See Figures 1 and 2 belw) Figure 1 Figure 2 C L High Speed Discharge The B, C, and G series can quickly discharge the utput capacitr (C L ) t avid applicatin malfunctin, when CE pin set lgic LOW t disable IC.

7 Output Vltage Discharge Characteristics CE Pin Functin The series enter the shut dwn mde, when a LOW lgic-level signal applies t the CE pin. In the shutdwn mde, IC current cnsumptin is ~0 µa (Typical value), with the Lx and V OUT pins at high impedance state. The IC starts its peratin when a HIGH lgic-level signal applies t the CE. Sft Start Sft start time is available in tw ptins via prduct selectin. The sft-start time f series is ptimized by using internal circuits. The definitin f the sft-start time is the time when the utput vltage ges up t the 90% f nminal utput vltage after the IC is enabled by CE H signal.

8 LAYOUT AND USE CONSIDERATIONS 1. Wire external cmpnents as clse t the IC as pssible and use thick, shrt cnnecting traces t reduce the circuit impedance. Please, pay special attentin t the V IN and GND wiring. Switching nise, which ccurs frm the GND, may cause the instability f the IC, s, psitin V IN and V CL capacitrs as clse t IC as pssible (See recmmended layut n the right). 2. Transitinal vltage drps r vltage rising phenmenn culd make the IC unstable if ratings are exceeded. 3. The series are designed t wrk with ceramic utput capacitrs. Hwever, if the difference between input and utput vltages is t high, a ceramic capacitr may fail t absrb the resulting high switching energy and scillatin culd ccur. In this case, cnnect an electrlytic capacitr in parallel t ceramic ne t cmpensate fr insufficient capacitance. 4. In PWM mde, IC generates very narrw pulses, and there is a pssibility that sme cycles will be skipped cmpletely, if the difference between V IN and V OUT is high. 5. If the difference between V IN and V OUT is small, IC generates very wide pulses, and there is a pssibility that sme cycles will be skipped cmpletely at the heavy lad current. 6. When drput vltage r lad current is high, Current Limit may activate prematurely that will lead t IC instability. T avid this cnditin, chse inductr s value t set peak current belw Current Limit threshld. Calculate the peak current accrding t the fllwing frmula: I PK = (V IN - V OUT ) x D / (2 x L x f OSC ) + I OUT, where L - Inductance f OSC -- Oscillatin Frequency D Duty cycle 7. Inductr s rated current exceeds Current Limit threshld f 1050 ma t avid damage, which may ccur until P-channel transistr turns ff after Current Limiter activates, but pulse current may exceed this value(see figure belw). Current flws int P-channel transistr reaches the current limit (I LIM). Current is mre than I LIM due the circuit s delay time frm the current limit detectin t the P-channel transistr OFF. The inductr s current time rate becmes quite small. IC generates very narrw pulses fr several millisecnds. The circuit latches, stpping peratin. 8. If V IN vltage is less than 2.4 V, current limit threshld may be nt reached due vltage drp caused by switching transistr s ON resistance 9. Latch time may becme lnger r latch may nt wrk due electrical nise. T avid this effect, the bard shuld be laid ut s that input capacitrs are placed as clse t the IC as pssible. 10. Use f the IC at vltages belw recmmended vltage range may lead t instability. 11. At high temperature, utput vltage may increase up t input vltage level at n lad, because f the leakage current f the driver transistr. 12. High step-dwn rati and very light lad may be cause f intermittent scillatins in PWM mde. 13. In PWM/PFM autmatic switching mde, IC may becme unstable during transitin t cntinuus mde.
