ADP5350 - Analog Devices

ADP5350 Advanced Battery Management PMIC

The ADP5350, a power management IC (PMIC), combines one high performance buck regulator for single Li-Ion/Li-Ion polymer battery charging, a fuel gauge, a highly programmable boost regulator for LED backlight illumination, and three 150 mA LDO regulators. The ADP5350 operates in trickle charge mode and in constant current (CC) and constant voltage (CV) fast .
