BL8529

BL8529 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. The BL8529 is available in the DFN2x2-8L and DFN3x3-10L package FEATURES Adjustable Output Voltage, Vfb=0.8V Maximum output current is 3A Range of operation input voltage: Max 6V Standby current: 0.5mA (typ.) Line regulation: 0.1%/V (typ.) Load regulation: 10mV (typ.) High efficiency, up to 96% Environment Temperature: -20°C~85°C APPLICATIONS Power Management for 3G modem 3W LED driver from Li-ion battery LCD Monitor and LCD TV DVD Decode Board ADSL Modem Post Regulators for Switching Supplies TYPICAL APPLICATION BL8529 PIN OUT & MARKING 1.EN_ 8.
