Features

* Primary-side sensing and regulation operates in CCM/QR mode without TL431 and opto-coupler
* High precision constant voltage and current regulation at universal AC input
* Fixed frequency (65kHz) CCM mode operation with low line voltage at full load
* Integrated 4A MOSFET
* Qua

Applications

* The device operates in CCM/QR mode to provide high efficiency along with several functions of built-in protections. It removes the need for secondary feedback circuitry to lower the total bill of material cost. Proprietary Constant Voltage (CV) and Constant Current (CC) control is integrated as sho
