AP3790 Datasheet (Diodes) - COMPATIBLE AC/DC PSR CONTROLLER

AP3790, COMPATIBLE AC/DC PSR CONTROLLER

Pin Assignments The AP3790 is a high accuracy and low cost switching mode power supply controller to drive power bipolar transistor for battery charger/adapter applications.

The controller regulates the output voltage and current in the primary side by piece-wise Pulse Frequency Modulation (p-PFM)

AP3790 Features
