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
