1.2A Integrated FETs, High Efficiency

Synchronous Buck Regulator

Features

• High Efficiency Synchronous Buck Regulator with Up to

95% Efficiency

ISL8011 is an integrated FET, 1.2A synchronous buck

regulator for general purpose point-of load applications. 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 from common 3.3V or 5V supply rails and Lithium ion

battery inputs. It has guaranteed minimum output current of

1.2A. 1.5MHz pulse-width modulation (PWM) switching

frequency allowing the use of small external components.

• 2.7V to 5.5V Supply Voltage

• 1.2A Guaranteed Output Current

• 100% Maximum Duty Cycle

• Peak Current Limiting, Short Circuit Protection

• 200ms Power-On Reset

The ISL8011 includes a pair of low on-resistance P-channel

and N-channel internal MOSFETs to maximize efficiency and

minimize external component count. 100% duty-cycle

operation allows less than 200mV dropout voltage at 1.2A.

• 3% Output Accuracy Over Temperature/Load/Line

• Less than 1µA Logic Controlled Shutdown Current

• Internal Loop Compensation

The ISL8011 offers a 200ms Power-On-Reset (POR) timer

at power-up. When shutdown, the ISL8011 discharges the

output capacitor. Other features include internal digital soft-

start, enable for power sequence, overcurrent protection,

and thermal shutdown.

• Internal Digital Soft-Start

• Over-Temperature Protection

• Enable

• Small 10 Ld 3x3mm DFN

The ISL8011 is offered in a 10 Ld 3x3mm DFN package with

1mm maximum height. The complete converter occupies

less than 1cm area.

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.
