APW8861 Overview
It offers the lowest total solution cost in system where space is at a premium. The APW8861 provides excellent transient response and accurate DC voltage output in either PFM or PWM Mode. In Pulse Frequency Mode (PFM), the APW8861 provides very high efficiency over light to heavy loads with loadingmodulated switching frequencies.
