Ann,

TPS63710 will not support that. For inverting buck boost you will need 36 - (-52) = 88 V. You will have to find a 100 V rated device. I will move this to the HV forum.

Ann, converter looks to be your only option based on input/output power requirements.

How about LM5146?

Hello Marshall,

Sorry for the TYPO, I need 19V~36V -> -52V/1.2A condition. I'm not sure if LM5146 could support this application. Thanks!

Best regards,
