描述 Description

High-Brightness Buck Controller LED Driver

DW8522 is a high efficiency step down (Buck) converter for LED driver IC which provide a solution for MR16, general lighting of flat panel displays and general DC voltage LED applications. DW8522 built in high-side current sensing circuit and protection circuit same as TSD and current limit. It can use PWM dimming and analog dimming. DW8522 are available in Small DFN package and a SOIC package.
