Other Parts Discussed in Thread: TLV431A, TL431
Hi,
My customer used UCC28C41 to design a flyback with 3.3V/100mA for MUC VCC, they disable the 15V output circuit for the test.
I refer to the spec for voltage mode setup to add 2N222, but now there work in the burst mode in 100mA now.
The L1 is 2mH now, Will increasing the transformer inductance help?
Can UCC28C41 work without burst mode? for MUC need stable voltage to make sure the normal operation.
There are better solutions to give the MUC Vcc power for isolation topology? thanks.
