BIT3267

Current Mode LED Driver

BIT3267 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 makes BIT3267 an ideal controller for LED backlight applications. Three sections frequency selection is suitable for variable system design. Internal soft start function can avoid inrush current during startup period. Over temperature protection and UVLO make system reliable. CMOS process greatly reduces the operating current compared with similar products.
