Overview

Preliminary Datasheet Primary Side Power Switcher for Off-line SMPS General Description The AP3968/69/70/70S consists of a primary side regulation controller and a high voltage transistor, and is specially designed for off-line power supplies within 12W output power.
Typical applications include adapter for ADSL and auxiliary supplies.
The AP3968/69/70/70S operates at pulse frequency modulation (PFM), and provides accurate constant voltage, constant current (CV/CC) regulation without requiring an opto-coupler and secondary control circuitry.
It has internal cable compensation function for tight constant voltage regulation.
The AP3968/69/70/70S solution has fewer component numbers, smaller si...
