General Description:
The BIT3260 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 current protection make
BIT3260 be an ideal controller for LED backlight
supplies. Frequency adjustable is flexible in
variable system design. Internal soft start function
can avoid inrush current happened in the start up
period. Over temperature protection and UVLO
make system reliable. CMOS process greatly
reduces the operating current when comparing to
similar products
