GENERAL DESCRIPTION
PS4509 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, PS4509 is featured a current ramp down function from 125oC to 145oC 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. 3-channel functions are integrated in PSOP-8 package.APPLICATIONS
