SSL21083DB01,598 is a buck reference design using SSL21083 highly integrated switching mode LED driver which enables constant current driving from the mains input. It is a solution for small LED retrofit lamp application, especially for low power factor design. The SSL21083 is a buck converter controller suitable for non isolated, non dimmable LED retrofit lamps. It can drive long LED strings with, typically 70V forward voltage. The SSL2108 series is intended to operate with higher output voltages, as present in modern LED modules. This board is intended to operate at 230V (AC), using an output voltage of 30V or more.
● SSL21083T IC used on the board
● Efficiency of 94%
● Power factor is 0.6
● Input voltage of 170VAC to 260VAC
● Output voltage of 20V to 130V (optimized for 70V LED)
● Output current of 96mA
● Maximum output power of 12.5W
