SDH790XSHN is designed for non-isolated LED driving with built-in high voltage power MOSFET and high voltage JFET. With this structure, inductor current is sensed and closed-loop is formed with the internal error amplifier for high constant current accuracy and high input/output regulation rate. Also, high PF in full range is available due to its own PFC control. Boundary Conduction mode is adopted for decreasing switching loss and improving the conversion efficiency.

SDH790XSHN can realize high power factor without any external integral capacitor.

Peripheral VCC pin and VCC capacitor (to GND) are unnecessary.

Over voltage protection threshold value is set through pin ROVP.

SDH790XSHN integrates various protections, such as output open circuit protection, output short circuit protection, cycle-by-cycle over current protection, and over temperature protection.

SDH790XSHN has ultra low start-up current and operating current, is able to high effectively drive highlight LED in full voltage input range.
