APM80904 Description
The APM80904 is a plete synchronous buck switching regulator module that provides constant current output to drive high-power LEDs. It integrates both high-side and low-side N-channel switches, inductor, high frequency VIN and boot capacitors. A true average current is output using a cycle-bycycle, controlled on-time method.
