Datasheet Summary
3A 1.5MHz 5.5V Synchronous Buck Converter
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.
