NU511 Overview
The NU511 is a single channel, open drain, linear constant current LED driver. With up to 1.2A driving current and maximum 1Mhz PWM dimming control support, NU511 can be used for 0.5W to 3W high power LED string in general or architecture decoration lighting applications. The wide power supply range capability makes NU511 work stably in uncertain power supply applications.
