TPS7H4010-SEP: Space Grade Boost Converter

Joaquin Mariano Piñeiro

Tool/software:

Hello, I have been searching in the entire web for some Boost Converter space grade or rad tolerant, but I couldn't find anything. Is there any solution that could be provided? Input is 12V and the output must be 18V, and the current capability is less than 500mA. I saw that sometimes one DC DC IC converter could be tweaked to behave like another, for example: https://www.ti.com/lit/an/snvaa76/snvaa76.pdf

Thanks,

Joaquín Mariano Piñeiro.

Hello Joaquín,

Per the Application Note you linked above (snvaa76) some buck converters can be configured as inverting buck-boosts. They will only output negative voltages.

We do not have an integrated-switch rad hard or rad tolerant boost converter in our portfolio at this time.

We do however have a single-switch boost controller, TPS7H5020, in both -SP and -SEP that is currently in preview, releasing soon.

The EVM for this product is a 5V to 15V, 1A boost converter with a GaN switching element. The TPS7H5020 also supports Si FETs.

Being a controller, much flexibility is afforded for a variety of applications.
