Overview

AN30888A/AN30888B is a LED driver LSI catering for wide power supply range and provides power supply to LED system for various applications. Based on PWM input, light adjustment functionluminance setting can be easily achieved making design with this LED driver LSI highly flexible.                                                                                
By using this product, boost /buck /boost-buck output system can be achieved by simply changing the external circuit. With wide power supply range of 3∼20V, the design for LED application becomes highly flexible.
As various power supplies including battery operation are supported, an optimum output system which satisfies the power supply and number of LED used can be set.
