Rad Hard and SEE Hard 6A Synchronous Buck Regulator

ISL70001ASEH

Features

The ISL70001ASEH is a radiation hardened and SEE hardened

high efficiency monolithic synchronous buck 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. Output load current capacity is 6A

• ±1% Reference Voltage Over Line, Load, Temperature and

Radiation

• Current Mode Control for Excellent Dynamic Response

• Full Mil-Temp Range Operation (T = -55°C to +125°C)

• 50% Lower Shutdown Supply Current than the ISL70001SEH

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

• Highly Efficient: 94% Peak Efficiency

for T < +145°C.

The ISL70001ASEH utilizes 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

OUT

from 0.8V to ~85% of V

• Bi-directional SYNC Pin Allows Two Devices to be Synchronized

180° Out-of-Phase

• Power-Good Output Voltage Monitor

• Adjustable Analog Soft-Start

The ISL70001ASEH incorporates fault protection for the

regulator. The protection circuits include input undervoltage,

output undervoltage, and output overcurrent.

• 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

Applications

• FPGA, CPLD, DSP, CPU Core or I/O Voltages

* Product capability established by initial characterization. The

EH version is acceptance tested on a wafer-by-wafer basis to

50krad(Si) at low dose rate.

• Low-Voltage, High-Density Distributed Power Systems
