FN6656.0

1.5A Low Quiescent Current 1.6MHz High

Efficiency Synchronous Buck Regulator

Features

• High Efficiency Synchronous Buck Regulator with up to

95% Efficiency

The ISL8009A is a high efficiency, monolithic, synchronous

step-down DC/DC regulator that can deliver up to 1.5A

continuous output current. It is optimized for generating low

output voltages down to 0.8V. The supply voltage range of

2.7V to 5.5V, allows the use of single Li+cell, three NiMH

cells or a regulated 5V input. The ISL8009A uses current

mode control architecture to deliver very low duty cycle

operation at high frequency with fast transient response and

excellent loop stability. It has flexible operation mode

selection of forced PWM mode and automatic PFM/PWM

with as low as 17µA quiescent current, achieving high power

conversion efficiency under light load condition, hence

maximizing battery life. High 1.6MHz pulse-width modulation

(PWM) switching frequency allows the use of small external

components.

• 2ms Reset Timer

• 2.7V to 5.5V Supply Voltage

• 3% Output Accuracy Over-Temperature/Load/Line

• 1.5A Guaranteed Output Current

• 17µA Quiescent Supply Current in PFM Mode

• Selectable Forced PWM Mode and PFM Mode

• Less Than 1µA Logic Controlled Shutdown Current

• 90% Maximum Duty Cycle for Lowest Dropout at 1.5A

• Internal Current Mode Compensation

• Internal Digital Soft-Start

The ISL8009A integrates a pair of low ON-resistance

P-Channel and N-Channel internal MOSFETs to maximize

efficiency and minimize external component count. The

100% duty-cycle operation allows less than 400mV dropout

voltage at 1.5A output current.

• Peak Current Limiting, Short Circuit Protection

• Over-Temperature Protection

• Enable

• Soft Discharge Disable

The ISL8009A offers a 2ms Power-On-Reset (POR) timer at

power-up. The timer output can be reset by RSI. When

shutdown, ISL8009A discharges the output capacitor

through a 100Ω resistor. Other features include internal

digital soft-start, enable for power sequence, overcurrent

protection, and thermal shutdown.

• Small 8 Ld 2mmx3mm DFN

• Pb-Free (RoHS Compliant)

Applications

• DC/DC POL Modules

• µC/µP, FPGA and DSP Power

• Plug-in DC/DC Modules for Routers and Switchers

• Portable Instruments

The ISL8009A is offered in a 2mmx3mm 8 Ld DFN package

with 1mm maximum height. The complete converter

occupies less than 1cm area.
