Radiation Hardened and SEE Hardened 6A

Synchronous Buck Regulator with Integrated MOSFETs

ISL70001SRH

Features

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 capacity is 6A

• Electrically Screened to DSCC SMD 5962-09225

• 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

for T < +145°C.

• SEE Hardness

- SEL and SEB LET . . . . . . . . . . . . 86.4MeV/mg/cm min

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

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 undervoltage lockout capability by

using two external resistors to precisely sense the level of an

external supply voltage. A power-good signal indicates when the

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

voltage.

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

Radiation

• Adjustable Output Voltage

• Excellent Dynamic Response

from 0.8V to ~85% of V

• 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 by

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

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.

• Starts Into Pre-Biased Load

Applications

• 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.

Detailed Electrical Specifications for these devices are contained

in SMD 5962-09225. This link is also available on the

ISL70001SRH device information page on the Intersil web site.
