AXP2101
Overview
AXP2101 is a highly integrated power management IC(PMIC) targeting at single cell Li-battery(Li-ion or Li-polymer) applications that require multi-channel power conversion outputs. It provides an easy and flexible power management solution for multi-core processors to meet the complex and accurate requirements of power control.
