40 pin,5x5mm2 QFN Package
AXP152 is a highly integrated power management IC that provides easy and flexible power solution for applications that require multi-rail outputs. It has fully met the increasingly complex needs of application processors on accurate power control.
AXP152 integrates four step-down converters (Buck DC-DC converter), seven low dropout regulators. It also features protection circuitry such as over/under-voltage protection (OVP/UVP), over-temperature protection, and over-current protection (OCP) to guarantee the power system security and stability.
In addition, AXP152 includes a Two Wire Serial Interface (TWSI), through which the application processor is capable of enabling/disabling some power outputs, programming the voltage to decrease the power consumption, and provides customers with unprecedented experience of power management
AXP152 is available in 5mm x 5mm 40-pin QFN package,
and the package is Pb free.
