TPS 40305 Rad-Hard Equivalent and Vbp reduction

Ansel Barchowsky
Prodigy 75 points

Hi all;

I am working on a project to develop low voltage, high current, point of load converters for spacecraft applications. I was wondering if I could get some insight on two topics for the TPS 40305.

First, I was curious if someone could provide a recommendation of a comparable TI component that is radiation hardened.

Second, I was wondering if there is anyway to reduce the outputs on HDRV and LDRV to 5V from their nominal value. These seem to be tied to Vbp, so if there is a way to alter that it would be equally useful.

Thank you very much,

Ansel
