Part Number: UCG28826 Other Parts Discussed in Thread: UCG28824 Hi,
I was looking into using the UCG28826 IC for a 12 W flyback converter. However the IC seems to be optimized to run at 65 W. Can you let me know if a 12 W design would be optimal?

Part Number: UCG28826 Hi sir,
Can UCG28826 use DC input but not AC? What would be the DC input voltage range?
Which spec in datasheet should I check for the DC input? What would be the circuit design for the DC input?
My customer has a 9Vdcin…
Part Number: UCG28826 Hi team,
Is there any start-up threshold other than Brown-in threshold at Vbulk?
Customer wants to understand start-up sequence to enable UCG28826 work as expected.

Part Number: UCG28826 HI team,
Could you please answer to questions from customer.
Datasheet 10.7.4.7 mentions Configure Error. What does it mean?
Could you let me know how the device behave when TR pin, IPK pin, FCL pin, and CDX pin become open…
Part Number: UCG28826 Tool/software: Hi Team,
Per datasheet's description - "The UCG2882x's burst mode offers three 1st valley QR switching cycles followed by a minimum 70μs delay before the start of next burst packet."
However, the 2nd or 3rd valley…
Part Number: UCG28826 Other Parts Discussed in Thread: UCG28824 Tool/software:
I will use the UCG2882x to design aux power 25W, but the UCG28826 is too high current limit to my design.
I think UCG28824 may be suitable. However, I can't find the…
Part Number: UCG28826 Tool/software: Hi TI,
As title question, it cause output voltage discharge very slow at light load and some timing issue on system.
See below waveform, after AC OFF, the PWM is still switching until Vbulk drops to low.
As my…
