Other Parts Discussed in Thread: LM3481

Hello,

Is there any solution to the following conditions?

- Input : 6 to 8.4V

- Output : 100V@300mA

I found the Reference Design for LM3481. http://www.ti.com/lit/ml/snvr141/snvr141.pdf

Is it possible to change the output (100V@10mA→100V@300mA)?

Could you tell me any better solution if it's difficult.

Best Regards,

Hi Hidetoshi,

We've attached a reference design for a stacked multiple output flyback (SEPIC between primary and first secondary). This approach provides true shutdown and proper current limiting in the event of an output short.
