External MOSFET

SM6300B is single technology based on the primary side feedback, high power factor AC-DC LED Driver IC. It requires minimal external components and can accurately control LED current without feedback using opt coupler or a secondary circuit. SM6300B integrated comprehensive protection features include cycle-by-cycle Limiting protection, output overvoltage protection, output short circuit protection and over-temperature protection to ensure LED system’s reliable work.
