Part Number: BIT3251

Function: Low Cost PWM Controller

Manufacturer: BiTEK

Pinouts:

BIT3251 datasheet

 

Description

The BIT3251 is a high frequency PWM controller integrates required fuctions 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.
