1.2A 1.6MHz Low Quiescent Current High

Efficiency Synchronous Buck Regulator

Features

• High Efficiency Integrated Synchronous Buck Regulator

with up to 95% Efficiency

ISL9106 is a 1.2A, 1.6MHz step-down regulator, which is

ideal for powering low-voltage microprocessors in compact

devices such as PDAs and cellular phones. It is optimized

for generating low output voltages down to 0.8V. The supply

voltage range is from 2.7V to 5.5V allowing 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. It has flexible

operation mode selection of forced PWM mode and Skip

• 2.7V to 5.5V Supply Voltage

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

• 1.2A Guaranteed Output Current

• 3% Output Accuracy Over Temperature/Load/Line

• Selectable Forced PWM Mode and Skip Mode

• Less than 1μA Logic Controlled Shutdown Current

• 100% Maximum Duty Cycle for Lowest Dropout

• Discharge Output Cap when Shutdown

• Internal Digital Soft-Start

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

highest light load efficiency to maximize battery life.

The ISL9106 integrates a pair of low ON-resistance

P-Channel and N-Channel MOSFETs to maximize efficiency

and minimize external component count.

• Peak Current Limiting, Short Circuit Protection

• Over-Temperature Protection

The ISL9106 offers a typical 215ms Power-Good (PG) timer

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

When shutdown, ISL9106 discharges the output capacitor.

Other features include internal digital soft-start, enable for

power sequence, overcurrent protection, and thermal

shutdown.

• Enable, Power Good Function

• 10 Ld 3mmx3mm DFN

• Pb-Free Plus Anneal Available (RoHS Compliant)

The ISL9106 is offered in 10 Ld 3mmx3mm DFN package

with 0.9mm typical height. The complete converter can

Applications

occupy less than 1cm area.

• Single Li-Ion Battery-Powered Equipment

• DSP Core Power

NOTE: Intersil Pb-free plus anneal products employ special Pb-free

material sets; molding compounds/die attach materials and 100%

matte tin plate termination finish, which are RoHS compliant and

compatible with both SnPb and Pb-free soldering operations. Intersil

Pb-free products are MSL classified at Pb-free peak reflow

temperatures that meet or exceed the Pb-free requirements of

IPC/JEDEC J STD-020.
