APW8821 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 puters. The APW8821 provides excellent transient response and accurate DC voltage output in either PFM or PWM Mode.
