SM2097 is a high precision step-down constant current LED driver chips. Chip inductor current critical work in continuous mode for 85Vac ~ 265Vac input voltage full range of non-isolated buck LED constant current power supply. SM2097 chip integrated 500V power switch, power detection and no auxiliary winding, making it easier to peripheral devices, saving the cost and size of the system.
SM2097 chip with high-precision current sampling circuit, high accuracy LED constant current output and excellent line voltage regulation. Chip inductor current critical work mode, output current with inductance and LED operating voltage changes varied to achieve excellent load regulation.
SM2097 has multiple protection features including LED short circuit protection, under-voltage protection, the chip overheating adjustment function. SM2097 use SOT23-3 package.
