BCD Semiconductor Manufacturing Limited AP3969
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. 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.| Part No. | AP3969 |
