cription The AP3968/69/70 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 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 solution has fewer component numbers, smaller size, and lower total c
