ISL71001M

6A Synchronous Buck Regulator with Integrated MOSFETs

The ISL71001M is a radiation tolerant and high

Features

efficiency monolithic synchronous buck regulator with

integrated MOSFETs. This single chip power solution

operates across 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 with an output load current capacity of 6A. The

ISL71001M is available in a plastic 64 Ld Thin Quad

Flatpack (EP-TQFP) package.

• Passes NASA low outgassing specifications

• Operates from 3V to 5.5V supply

• Programmable power-on reset level

• Current mode control for excellent dynamic response

• Fixed 1MHz switching frequency

• ±1.2% reference voltage

The ISL71001M 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 applications where two regulators are needed, two

ISL71001M 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.

• Thermally enhanced heat-sink plastic package

• Highly efficient: 95% peak efficiency

• Bidirectional SYNC pin allows two devices to be

synchronized 180° out-of-phase

• Adjustable output voltage

• Analog soft-start

• Output undervoltage and output overcurrent

protection

The ISL71001M incorporates fault protection for the

regulator. The protection circuits include input

undervoltage, output undervoltage, and output

overcurrent.

• Power-good output voltage monitor

• Tin (Sn) free lead finish

• Characterized radiation level

• 30krad(Si) at a low dose rate

High integration makes the ISL71001M 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.

• Single-event effects at LET = 43MeV•cm /mg

Applications

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

• Low-voltage, high-density distributed power systems

• Low Earth Orbit (LEO) applications

• High altitude avionics

• Launch vehicles
