Description: COMPATIBLE AC/DC PSR SWITCHER

Features

* Compatible to MediaTek Pump ExpressTM Protocol
* Ultra-Low Standby Power Consumption
* Built-in NPN Transistor with 700VCBO
* Valley-turn On to Reduce Switching Loss and Benefit for EMI
* Piece-wise Frequency Reduction to Enhance Conversion Efficiency and Suppress Audio Noise

Applications

* It is consists of a primary side regulation controller and a high voltage transistor. The controller regulates the output voltage and current in the primary side by piece-wise Pulse Frequency Modulation (p-PFM) in discontinuous conduction mode (DCM). The switcher uses adaptive source current to opt
