External MOSFET

SM7385 is a non-isolation Buck type control IC with active power factor correction function for LED lighting application. The IC achieves high power factor and high efficiency by BCM mode. The line and load regulation of LED current is about ±2.5% because of particular control method.

SM7385 also provides gate driving voltage clamping, VCC over voltage protection and system output open/short circuit protection to increase IC performance.
