Exar - AEC-Q100 Qualified Current Regulator XR46004-Q


2018年 1月30日


Exar Launches AEC-Q100 Qualified 600mA High Voltage Adjustable Current Regulator XR46004-Q with Enable Control

The XR46004-Q is a high voltage, low dropout current regulator of output current up to 600mA in maximum. Users can adjust the output current from 100mA to 600mA through an external resistor, RSET, which gives users flexibility in controlling the light intensity of the LEDs. Further, the LED brightness is adjustable via the OE pin with a Pulse Width Modulation signal.
The thermal protection function protects the IC from over temperature damage. Also, the exposed thermal pad enhances the package power dissipation.
