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 Frequ

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 functi
