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.
• 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
