General Description
The APW8816 is a single-phase, constant on-time, synchronous PWM controller with linear regulator, which drives N-channel MOSFETs. The APW8816 steps down high voltage to generate low-voltage chipset or RAM supplies in notebook puters. The APW8816 provides excellent transient response and accurate DC voltage output in either PFM or PWM Mode. In Pulse Frequency Mode (PFM), the APW8816 provides very high efficiency over light to heavy loads with loadingmodulated switching...
