1.5A 1.6MHz Low Quiescent Current High

Efficiency Synchronous Buck Regulator

Features

• Integrated Synchronous Buck Regulator with up to 95%

Efficiency

ISL9107 and ISL9108 are 1.6MHz synchronous step-down

regulators with integrated power switches capable of

delivering 1.5A output current, which is ideal for powering

low-voltage microprocessors in compact devices such as

PDAs and cellular phones. These devices are optimized for

generating low output voltages down to 0.8V. The supply

voltage range is from 2.7V to 5.5V allowing for the use of a

single Li+ cell, three NiMH cells or a regulated 5V input.

1.6MHz pulse-width modulation (PWM) switching frequency

allows using small external components. They have flexible

operation mode selection of forced PWM mode and Skip

• 2.7V to 5.5V Supply Voltage

• 1.5A Guaranteed Output Current

• 17μA Quiescent Supply Current in Skip (Low I ) Mode

• Selectable Forced PWM Mode and Skip Mode

• Less Than 1µA Logic Controlled Shutdown Current

• 100% Maximum Duty Cycle for Lowest Dropout

• Discharge Output Capacitor when Shutdown

• Internal Digital Soft-Start

(Low I ) mode with typical 17μA quiescent current for

highest light load efficiency to maximize battery life.

• Enable, Peak Current Limiting, Short Circuit Protection

• Over-Temperature Protection

The ISL9107 and ISL9108 integrate a pair of low

ON-resistance P-Channel and N-Channel MOSFETs to

maximize efficiency and minimize external component

count.

• Power-Good Function (for ISL9107 only)

• 8 Ld 2mmx3mm DFN

The ISL9107 offers a typical 215ms Power-Good (PG) timer

when powered up. The timer output can be reset by RSI.

When shutdown, ISL9107 and ISL9108 discharge the output

capacitor. Other features include internal digital soft-start,

enable for power sequence, overcurrent protection, and

thermal shutdown.

• Pb-Free (RoHS Compliant)

Applications

• Single Li-Ion Battery-Powered Equipment

• DSP Core Power

The ISL9107 and ISL9108 are offered in 8 Ld 2mmx3mm

DFN package with 0.9mm typical height. The complete

• PDAs and Palmtops

converter can occupy less than 1cm area.
