General Description
PS4506 is a 3-channel LED driver with constant current regulator. PS4506 offers excellent temperature stability and output current accuracy with a wide input voltage from 7V to 40V and temperature range. PS4506 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, PS4506 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 VDDA/B/C and OUTA/B/C is designed as 60V ability to handle high voltage pulse suddenly....
