BIT3251
Low Cost LED Driver
BIT3251 is a high frequency PWM controller integrating required functions for boost conversion in a small SOP-8 package. A low 0.2V feedback voltage and over voltage protection make BIT3251 an ideal controller for LED backlight supplies. CMOS process greatly reduces the operating current compared to similar products.
