APW8745 Description
The APW8745 steps down high voltage to generate low-voltage chipset or RAM supplies in notebook puters. The APW8745 provides excellent transient response and accurate DC voltage output in either PFM or PWM Mode. In Pulse Frequency Mode (PFM), the APW8745 provides very high efficiency over light to heavy loads with loadingmodulated switching frequencies.
