Radiation Hardened and SEE Hardened 6A

Synchronous Buck Regulator with Integrated

MOSFETs

ISL70001SRH

Features

• Electrically Screened to DSCC SMD 5962-09225

The ISL70001SRH 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

• QML Qualified per MIL-PRF-38535 Requirements

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

+125°C)

• Radiation Hardness

- Total Dose [50-300rad(Si)/s] . . . 100krad(Si) min

capacity is 6A for T < +145°C.

• SEE Hardness

- SEL and SEB LET

The ISL70001SRH utilizes peak current-mode control

with integrated compensation and switches at a fixed

frequency of 1MHz. Two ISL70001SRH devices can be

synchronized 180° out-of-phase to reduce input RMS

ripple current. These attributes reduce the number and

size of external components required, while providing

excellent output transient response. The internal

synchronous power switches are optimized for high

efficiency and good thermal performance.

• High Efficiency > 90%

• Fixed 1MHz Operating Frequency

• Operates from 3V to 5.5V Supply

• ±1% Reference Voltage over Line, Load,

Temperature and Radiation

The chip features a comparator type enable input that

provides flexibility. It can be used for simple digital

on/off control or, alternately, can provide

• Adjustable Output Voltage

undervoltage lockout capability by precisely sensing

the level of an external supply voltage using two

external resistors. A power-good signal indicates

when the output voltage is within ±11% typical of the

nominal output voltage.

~85% of V

• Excellent Dynamic Response

• Bi-directional SYNC Pin Allows Two Devices to be

Synchronized 180° Out-of-Phase

Regulator start-up is controlled by an analog soft-start

circuit, which can be adjusted from approximately 2ms

to 200ms using an external capacitor.

• Device Enable with Comparator Type Input

• Power-Good Output Voltage Monitor

• Adjustable Analog Soft-Start

The ISL70001SRH 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

• Starts Into Pre-Biased Load

High integration makes the ISL70001SRH 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.

Applications*(see page 16)

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

• Low-Voltage, High-Density Distributed Power

Systems

Specifications for Rad Hard QML devices are

controlled by the Defense Supply Center in

Columbus (DSCC). The SMD numbers listed in the

Ordering Information Table on page 2 must be

used when ordering.
