High-Performance Notebook PWM Controller· Adjustable
High-Performance Notebook PWM Controller· Adjustable Output Voltage from +0.7V to +5.5V
- 0.7V Reference Voltage
- ±1% Accuracy Over-Temperature
· Operates from an Input Battery Voltage Range of
+1.8V to +28V
· Power-On-Reset Monitoring on VCC PinThe APW8828 is a single-phase, constant-on-time,
synchronous PWM controller, which drives N-channel
MOSFETs. The APW8828 steps down high voltage to
generate low-voltage chipset or RAM supplies in notebook
computers.
The APW8828 provides excellent transient response and
accurate DC voltage output in either PFM or PWM Mode.
In Pulse Frequency Mode (PFM), the APW8828 provides
very high efficiency over light to heavy loads with loadingmodulated
switching frequencies. In PWM Mode, the
converter works nearly at constant frequency for low-noise
l Compliant with Universal Serial Bus Specifica
