XR46014
XR46014 is High Voltage Constant Current Regulator manufactured by MaxLinear.
Description
The XR46014 is an 80V constant current regulator that can drive upto 250m A. Users may adjust the regulating current from 10m A to 250m A through an external resistor.
A linear type over temperature protection function protects the system by decrease the current linearly when the junction temperature of the chip is higher than 125°C. Multiple XR46014 chips can be connected in parallel to provide higher driving current capability.
The device is available in the SOT-223-3L package.
