Description	80V 1A High Efficiency Buck PFM LED Constant Current Driver
Datasheet	HM9802-H&MSemiconductor.pdf

The HM9802 is a monolithic high voltage switching regulator with PFM that is specifically designed to operate from a 12V~80V DC power supply.

The HM9802 is a high efficiency LED driver switching regulator.

The LED string is driven at DC constant current rather than constant voltage, thus providing constant light output and enhanced reliability.
