Hi Hong,
Thanks for the response .
I have tested the below ckt recently whcih is designed accordance with Ti webench and UCC28C56H Q1 EVB references. pls verify.
I have observed huge VDS spike across the Flyback switch, also the Vout of flyback is held…
Part Number: UCC28C56H-Q1 Other Parts Discussed in Thread: UCC28C56H , UCC24612 Dear Team,
I am designing Flyback with UCC28C56H-Q1 for the below specs. As you can see the Transient voltage at input side is for 5sec and remaining times the Steady state…
Part Number: UCC28C56H-Q1 Dear Team
could you pls help with max IDD required for the IC for the below condition?
Fsw = 110kHz
Qg = 36nC
As per our calculations:
IDD = IOUT+Isupply
IDD = 4mA + Isupply
Isupply i can see in the datasheet it varies with…

Hi Lilian,
1. Compensator zero design: C28 and R29 have good values considering a BW=fsw/10. However, C10 should be very low compared with C28 to add a high frequency pole to compensate the gain of the compensator zero. I recommend using C10=C28/10=10nF…
Part Number: UCC28C56H Hello,
is it possible to drive a PWM signal into the RT/CT pin rather than installing R & C? if not possible, can you recommend a part that allows this function?
thank you.
