APW8821 Notebook PWM Controller with Differential Voltage Feedback Features Adjustable Output Voltage from +0.5V to +3.3V - 0.5V Reference Voltage - +0.6% Accuracy General Description The APW8821 is a single-phase, constant on-time, synchronous PWM controller, which drives N-channel MOSFETs. The APW8821 steps down high voltage to generate low-voltage chipset or RAM supplies in notebook computers. The APW8821 provides excellent transient response and accurate DC voltage output in either PFM o
