3A 1.5MHz 5.5V Synchronous Buck Converter

BL8529

DESCRIPTION

The BL8529 is a high efficiency synchronous, buck

DC/DC converter. Its input voltage range is from

2.6V to 6V and provides an adjustable regulated

output voltage from 0.8V to 5.5V while delivering

up to 3A of output current.

The internal synchronous switches increase

efficiency and eliminate the need for an external

Schottky diode. The switching frequency is set by

an external resistor or can be synchronized to an

external clock. The 100% duty cycle provides low

dropout operation extending battery life in

portable systems.

The BL8529 is operated in PFM/PWM auto-switch

mode which enhance the efficiency at light-load.

The BL8529 is available in the DFN2x2-8L and

DFN3x3-10L package
