APW8728
VGA PWM Controller with Differential Voltage Feedback
Features
Adjustable Output Voltage from +0.6V to +3.3V - 0.6V Reference Voltage - ±0.6% Accuracy Over-Temperature
General Description
The APW8728 is a single-phase, constant on-time, synchronous PWM controller, which drives N-channel MOSFETs. The APW8728 steps down high voltage to generate low-voltage chipset or RAM supplies in notebook computers. The APW8728 provides excellent transient response and accurate DC voltage output in
