PT16753 Overview
The PT16753 is buck topology switching regulator with constant current output for high-power LEDs driving purpose. It integrates a 50V high side Nchannel MOSFET switch for step down conversion. The output current control loop operating in average current mode and the switch current is controlled cycle-by-cycle with an adaptive on-time structure.
