Part Number: LM73605
Other Parts Discussed in Thread: LMR36015, LMR23630

Can we use LM73605 for inverting output?

Using condition is 12Vin, -15Vout, 100mA. And Forced PWM operation is required.

We would like to know whether we can use LM73605. And please let me know if you have any other good solution.

The LM73605 can do it with no issue.

But it is a 5A part, way larger than you actually need. There are a few other options:

LMR23630FDRR: adj frequency, FPWM, WSON, 3A
LMR23630AFDDA: fixed 400kHz, FPWM, SOIC package, 3A

LMR36015 is also a good fit for this, 1.5A part. But it is in preview now and samples are available. The release date should be around the end of the year.

Yang-san,

Thank you for your response.
OK, I understood. I will suggest LMR23630 if our customer doesn't require PG function.
