BIT3260
Low Cost LED Driver
Features
General Description
BIT3260 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 BIT3260
an ideal controller for LED backlight supplies.
CMOS process greatly reduces the operating
current compared with similar products.
