General Description

BIT3368 is a high frequency PWM controller

integrating required functions for boost conversion

in a small SOP-8 package. A low 0.21V feedback

voltage, over voltage protection, over current

protection and load short protection make BIT3368

an ideal controller for LED backlight supplies.

Frequency selection is flexible in variable system

design. Internal soft start function can avoid inrush

current during start-up period. Over temperature

protection and UVLO make system reliable. CMOS

process greatly reduces the operating current

compared with similar products.
