APW8828
High-Performance Notebook PWM Controller
Features
General Description
• Adjustable Output Voltage from +0.7V to +5.5V
The APW8828 is a single-phase, constant-on-time,
- 0.7V Reference Voltage
synchronous PWM controller, which drives N-channel
- ±1% Accuracy Over-Temperature
MOSFETs. The APW8828 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.
• Power-On-Reset Monitoring on VCC Pin
The APW8828 provides excellent transient response and
• Excellent Line and Load Transient Responses
accurate DC voltage output in either PFM or PWM Mode.
