Data Sheet

October 29, 2007

FN6575.0

Enhanced Product (EP) 6.0A Dual

Synchronous Buck Regulator with

Integrated MOSFETs

Features

• Specifications per DSCC VID V62/07639

• Full Mil-Temp Electrical Performance from -55°C to +125°C

The ISL65426MREP is a high efficiency dual output

• Controlled Baseline with One Wafer Fabrication Site and

One Assembly/Test Site

monolithic synchronous buck converter operating over an

input voltage range of 2.5V to 5.5V. This single chip power

solution provides two output voltages which are selectable or

externally adjustable from 1.2V to 80% of the supply voltage

while delivering up to 6.0A of total combined output current

• Full Homogeneous Lot Processing in Wafer Fab

• Current Density Validated per MIL-PRF-38535

• Full Traceability Through Assembly and Test by

Date/Trace Code Assignment

when used at T of +125°C or less. The two PWMs are

synchronized 180° out of phase reducing the RMS input

current and ripple voltage.

• Enhanced Process Change Notification

• Enhanced Obsolescence Management

• Eliminates Need for Up-Screening a COTS Component

• High Efficiency of up to 90%

The ISL65426MREP switches at a fixed frequency of 1MHz

and utilizes current-mode control with integrated

compensation to minimize the size and number of external

components. The internal synchronous power switches are

optimized for good thermal performance, high efficiency,

and eliminate the need for an external Schottky diode.

• Fixed Frequency: 1MHz

• Operates From 2.5V to 5.5V Supply

• ±2.0% Reference

A unique power block architecture allows partitioning to

support one of four configuration options. One master

power block is associated with each synchronous converter

channel. Four floating slave power blocks allow the user to

assign them to either channel. Proper external

configuration of the power blocks is verified internally prior

to soft-start initialization.

• Flexible Output Voltage Options

- Programmable 2-Bit VID Input

- Adjustable Output From 1.2V to 4.0V

• Power Blocks are Rated at:

- 1A typ for T < +125°C and VIN Range 4.0V to 5.5V

- 0.7A typ for T < +125°C and VIN Range 2.5V to 5.5V

Independent enable inputs allow for synchronization or

sequencing soft-start intervals of the two converter

channels. A third enable input allows additional sequencing

for multi-input bias supply designs. Individual power good

indicators (PG1, PG2) signal when output voltage is within

regulation window.

• Ultra-Compact DC/DC Converter Design

• PWMs Synchronized 180° Out of Phase

• Independent Enable Inputs and System Enable

• Independent Output Digital Soft-Start

• Power Good Output Voltage Monitor

The ISL65426MREP integrates protection for both

• Short-Circuit and Thermal-Overload Protection

• Overcurrent and Undervoltage Protection

synchronous buck regulator channels. The fault conditions

include overcurrent, undervoltage, and IC thermal monitor.

High integration contained in a thin Quad Flat No-lead

(QFN) package makes the ISL65426MREP an ideal choice

to power many of today’s small form factor applications. A

single chip solution for large scale digital ICs, like field

programmable gate arrays (FPGA), requiring separate core

and I/O voltages.

Applications

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

• Point-of-Load Regulation in Distributed Power Systems
