APW8728
VGA PWM Controller with Differential Voltage Feedback
Features
General Description
• Adjustable Output Voltage from +0.6V to +3.3V
The APW8728 is a single-phase, constant on-time,
- 0.6V Reference Voltage at Internal Mode
synchronous PWM controller, which drives N-channel
- ±0.6% Accuracy Over-Temperature
MOSFETs. The APW8728 steps down high voltage to
• Operates from An Input Battery Voltage Range of generate low-voltage chipset or RAM supplies in notebook
+1.8V to +28V
computers.
• REFIN Function for Over-clocking Purpose from The APW8728 provides excellent transient response and
accurate DC voltage output in either PFM or PWM Mode.
