SD6921ASTR Datasheet | Silan Microelectronics

DESCRIPTION SD692XS is designed for non-isolated LED driving with floating Buck structure and built-in MOSFET. 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 as its own PFC control. Boundary Conduction mode is adopted for decreasing switching loss and improving the conversion efficiency. SOP-7-225-1.27 SD692XS integrates various protections, such as output open circuit protection, output short circuit protection, cycle-by-cycle current limit protection, and over temperature protection. SD692XS has a built-in VCC regulator, which allows periphery operating without auxiliary winding and makes output voltage range maximized. The start-up current and operating current are low and highlight LED can APPLICATION be driven with high efficiency in full range (85VAC~265VAC).
