AP3966, AP3965 PRIMARY SIDE POWER SWITCHER

AP3966 Description

A Product Line of Diodes Incorporated AP3965/66/71 PRIMARY SIDE POWER SWITCHER FOR FLYBACK/NON-ISOLATED BUCK SMPS .
The AP3965/66/71 consists of a primary side regulation controller and a high voltage transistor, and is specially designed for off-line power supplies.

AP3966 Features

* Primary Side Control for Eliminating Opto-coupler and Secondary CV/CC Control Circuitry
* Built-in NPN Transistor with 700VCBO
* Low Start-up Current: 0.2µA (Typ)
* Internal Output Cable Voltage Drop Compensation
* Random Frequency Modulation for Low EMI

AP3966 Applications

* within 5W. Typical applications include adapter for ADSL, auxiliary supplies or open frame types for appliances. The AP3965/66/71 operates at pulse frequency modulation (PFM), and provides accurate constant voltage, constant current (CV/CC) regulation without requiring an opto-coupler and secondary
