BIT3251

Low Cost LED Driver

BIT3251 is a high frequency PWM controller integrating required functions for boost conversion in a small SOP-8 package. A low 0.2V feedback voltage and over voltage protection make BIT3251 an ideal controller for LED backlight supplies. CMOS process greatly reduces the operating current compared to similar products.

Features:

  • Voltage Mode PWM Controller

  • 330KHz Operation
  • 4.5V to 10V Input Range
  • Over Voltage Protection
  • Internal Soft-Start
  • Internal UVLO (Under Voltage Lock Out)
  • Limited Output Duty Cycle
  • Low Shutdown Current (0.1uA)
  • CMOS Totem Pole Output
  • SOP-8 Package
