Overview
Description
The ISL70001ASEHEV1Z evaluation board is used to evaluate the ISL70001ASEH TID and SEE radiation hardened 6A synchronous buck regulator IC with integrated MOSFETs.
The ISL70001ASEHEV1Z evaluation board accepts a nominal 3V to 5.5V input voltage and provides a regulated output voltage ranging from 0.8V to 85% of the input voltage at output currents ranging from 0A to 6A. The output can be quickly set to any of six commonly used preset voltages (0.8V, 1.0V, 1.2V, 1.8V, 2.5V, 3.3V) or adjusted to an alternate voltage using the onboard potentiometer. A Power-Good (PGOOD) signal goes high and lights a red LED to indicate that the output voltage is within a ±11% typical regulation window. A toggle switch is provided to conveniently enable or disable the output voltage.
Features

16 of Intersil radiation-hardened ICs were onboard the December 5, 2014 maiden voyage of NASA's Orion spacecraft, also known as the uncrewed Exploration Flight Test 1. These rad-hard ICs are deployed in Orion's crew module, where they are used to support subsystems for mission critical applications in power distribution, navigation and flight control, and in the inertial measurement unit.
