VOUT1 as Its Power Supply) The APW8822/A/B/C integrates dual step-down, constant- • Excellent Line/Load Regulations about ±1.5% Over- on-time, synchronous PWM controllers (that drives dual Temperature Range N-channel MOSFETs for each channel) and two low drop- • Built in POR Control Scheme Implemented out regulators as well as various protections into a chip.
• Constant On-Time Control Scheme with Frequency The PWM controllers step down high voltage of a battery Compensation for PWM Mode to generate low-voltage for NB applications.
The output • Selectable Switching Frequency in PWM Mode of PWM1 and PWM2 can be adjusted from 2V to 5.5V by • Built-in Digital Soft-Start for PWM Outputs and Soft- setting a resistive voltage-divider from VOUTx to GND.
