Other Parts Discussed in Thread: UCC28742, LM5023
HI,
The VCC voltage of LM5021 is too low, and the customer needs a voltage of around 12-15V. Are there any similar devices that can be recommended?
Thanks!

Hello,
Thanks for reaching out, may I advise the input and output power level of your project?
Unfortunately, there are no pin to pin devices to LM5021.
But for cost concerns, UCC28742 may be your option for a Secondary-side regulated flyback controller that is SOT23-6 packaged. No need for VCC pin concerns anymore.
For better efficiency, LM5023 is a quasi-resonant current mode PWM controller that is in VSSOP8 package. VCC pin controller enable threshold is 12.8V.
THanks.
