XR46014ISETR

XR46014 Product Brief High Voltage Constant Current Regulator Description The XR46014 is an 80V constant current regulator that can drive upto 250mA. Users may adjust the regulating current from 10mA to 250mA through an external resistor. A linear type over temperature protection function protects the system by decrease the current linearly when the junction tempareture 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. Typical Application FEATURES ■■ 3V to 80V operation range ■■ 270mV low current sense voltage ■■ Linear over temperature protection ■■ Can be parallel connected for higher current APPLICATIONS ■■ LED Lighting Applications Downlight High bay Specialty Architectural Pin Configuration + – VAC LED BD 2 C RZ 1 2 3 CS GND IN Q1 XR46000 ZD U1 XR46014 IN GND CS RCS SOT-223 1/2 XR46014 Product Brief Ordering Information(1) Part Number XR46014ISETR Operating Temperature Range Lead-Free Package Packaging Method -40°C ≤ TJ ≤ 125°C Yes(2) SOT-223 Tape and reel XR46014-EVB Evaluation board for XR46014 NOTE: 1.
