APW8731C Description
The APW8731C is a dual-phase PWM control IC which provides a precision voltage regulation system and supports wide input range from 5.4V to 24V. By integrating dual-phase power MOSFET drivers and controller into the one IC, APW8731C can reduce the number of external ponents for a cost and space saving power management solution. The APW8731C's PWM controller adopts constant on time architecture which has the trait of...
