on-time, synchronous PWM converter with 24Ω N- 5V Output - 0.
6V Reference Voltage - Excellent Line/Load Regulations about +1.
5% over temperature range at PWM Channel • Built in POR Control Scheme Implemented • 15mA 5V Voltage Output channel high side MOSFET and 14Ω N-channel low side MOSFET, as well as various protections into a chip.
The PWM converter step down high voltage of a battery to generate low-voltage, for NB applications.
The APW8807 provides excellent transient response and accurate DC output voltage in automatic PFM/PWM Mode.
In Pulse-Frequency Mode (PFM), the APW8807 provides • Constant On-Time Control Scheme with Frequency very high efficiency over light to heavy loads with loading- Compensation for PWM Mode modulated switching frequencies.
The PWM mode works • Built in Soft Start for PWM Output and Soft Stop nearly at constant frequency for low-noise requirements.
for PWM Output and LDO Output The APW8807 is equipped with accurate sourcing • Integrated Bootstrap Forward P-CH MOSFET current-limit, output under-voltage, output over-voltage • High Efficiency over Light to Full Load Range protections, being perfect for NB applications.
