APW8822E
Overview
- Wide Input voltage Range from 6V to 25V
- Provide 5 Independent Outputs with ±1.0% Accu- racy 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
- 3V Output - 270kHz Clock Signal for 15V Charge Pump (Used General Description VOUT1 as Its Power Supply) The APW8822E integrates dual step-down, constant-on-
- Excellent Line/Load Regulations about ±1.5% Over- time, synchronous PWM controllers (that drives dual N- Temperature Range 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. Stop for PWM Outputs and LDO Outputs The linear regulators provide 5V and 3.3V output for
- Integrated Bootstrap Forward P-CH MOSFET standby power supply. The linear regulators provide up
- High Efficiency over Light to Full Load Range to 100mA output current. When the PWMx output voltage (PWMs) is higher than LDOx bypass threshold, the related LDOx
