XS4505
Description
XS4505 is a single channel LED driver with constant current regulator. XS4505 offers excellent temperature stability and output current accuracy (±3.5%) with a wide input voltage from 4.5V to 40V and temperature range. XS4505 implements various fixed output current versions without external current setting resistors and thus creates a simple solution for constant current LED driver. Besides, for the thermal management in LED, XS4505 is featured a current ramp down function from 125o C to 145o C of junction temperature. Moreover, taking reliability into consideration, the maximum voltage rating on VDD, VP and VN is designed as 60V ability to handle high voltage pulse suddenly. Thoughtfully, XS4505 also supports both high-side and low-side driving for the LED strings. XS4505 is available in the cost-effective package SOT23-3.
