Rad Hard 6A/9A Buck Regulator Evaluation Boards


The ISL70003SEHEV1Z evaluation board is designed to evaluate the performance of the ISL70003SEH, a TID and SEE hardened 6A synchronous buck regulator IC with integrated MOSFETs intended for space applications.

The ISL70003ASEHEV2Z evaluation board is designed to demonstrate the performance of the ISL70003ASEH product as a 12V input to 3.3V output, 6A output current POL regulator, making it ideal for wiring into an existing circuit.

The ISL70003SEHEV1Z and ISL70003ASEHEV2Z evaluation boards accept a nominal input voltage of 12V and provides a regulated output voltage of 3.3V with output current ranging from 0A to 6A. There is a green LED indicating PGOOD.
