ISL70001ASEH

Radiation Hardened and SEE Hardened 6A Synchronous Buck Regulator

FN8365

Rev.3.03

Sep 16, 2022

The ISL70001ASEH is a radiation hardened and SEE

Features

hardened high-efficiency monolithic synchronous buck

• ±1% reference voltage over line, load, temperature and

radiation

regulator with integrated MOSFETs. This single chip power

solution operates over an input voltage range of 3V to 5.5V

and provides a tightly regulated output voltage that is

externally adjustable from 0.8V to ~85% of the input voltage.

• Current mode control for excellent dynamic response

• Full mil-temp range operation (T = -55°C to +125°C)

Output load current capacity is 6A for T < +145°C.

• 50% lower shutdown supply current than the ISL70001SEH

• Available in a thermally enhanced heatsink package - R48.B

• Highly efficient: 94% peak efficiency

The ISL70001ASEH uses peak current-mode control for

excellent output load transient response and features

integrated compensation and switches at a fixed frequency of

1MHz to reduce component size and count. In application

where two POLs are needed, two ISL70001ASEH devices can

be synchronized 180° out-of-phase to reduce the overall input

RMS ripple current. The internal synchronous power switches

are optimized for high efficiency and good thermal

performance.

• Operates from 3V to 5.5V supply

• Adjustable output voltage

- Two external resistors set V

from 0.8V to ~85% of V

OUT

• Bidirectional SYNC pin allows two devices to be

synchronized 180° out-of-phase

The ISL70001ASEH incorporates fault protection for the

regulator. The protection circuits include input undervoltage,

output undervoltage, and output overcurrent.

• Power-good output voltage monitor

• Adjustable analog soft-start

• Input undervoltage, output undervoltage and output

overcurrent protection

High integration and class leading radiation tolerance makes

the ISL70001ASEH an ideal choice to power many of today’s

small form factor applications. Two devices can be

synchronized to provide a complete power solution for large

scale digital ICs, like field programmable gate arrays

(FPGAs), that require separate core and I/O voltages.

• Electrically screened to DLA SMD 5962-09225

• QML qualified per MIL-PRF-38535 requirements

• Radiation acceptance testing
