APW8811 Description
The APW8811 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. The PWM controllers step down high voltage of a battery to generate low-voltage for NB applications. The output of PWM1 and PWM2 can be adjusted from 2V to 5.5V by setting a resistive voltage-divider from...
