XR46004 600mA High Voltage Adjustable Current Regulator with Enable Control August 2, 2021 Description FEATURES The XR46004 is a high voltage, low dropout current regulator of output 600mA maximum output current current up to 600mA in maximum. Users can adjust the output current Output current adjustable via external resistor from 100mA to 600mA through an external resistor, RSET, which 3s fast response output stage enable gives users flexibility in controlling the light intensity of the LEDs. control Further, the LED brightness is adjustable via the OE pin with a Pulse Output sustaining voltage up to 75V Width Modulation signal. Wide supply voltage range: 5V to 50V The thermal protection function protects the IC from over temperature TO-252-5L package Green package damage. Also, the exposed thermal pad enhances the package power dissipation.
