APW8812 - System Power PWM Controller

General Description

The APW8812 integrates dual step-down, constant-ontime, synchronous PWM controllers (that drives dual Nchannel MOSFETs for each channel) and two low dropout regulators as well as various protections into a chip.

Key Features

  • Wide Input voltage Range from 6V to 25V Provide 5 Independent Outputs with ±1.5% Accuracy Over-Temperature - PWM1 Controller with Adjustable (2V to 5.5V) Output - PWM2 Controller with Adjustable (2V to 5.5V) Output - 100mA Low Dropout Regulator (LDO5) with Fixed 5V Output - 100mA Low Dropout Regulator (LDO3) with Fixed 3.3V Output - 270kHz Clock Signal for 15V Charge Pump (Used VOUT1 as Its Power Supply) Excellent Line/Load Regulations about ±1.5% OverTemperature Range ±1%, (.
