The APW8802 steps down high voltage to generate low-voltage chipset or RAM supplies in notebook computers. The APW8802 provides excellent transient response and accurate DC voltage output in either PFM or PWM Mode. In Pulse Frequency Mode (PFM), the APW8802 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-noi...
