BIT3368
Current Mode LED Driver
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.
