General Description:

The BIT3251 is a high frequency PWM controller

integrates required functions for boost conversion in a

small SOP-8 package. A low 0.2V feedback voltage

and over voltage protection make the BIT3251 be an

ideal controller for LED backlight supplies. CMOS

process greatly reduces the operating current when

comparing to similar products.
