BIT3269
Low Cost LED Driver
BIT3269 integrated circuit provides essential PWM features for white LED driver. It can drive up to 27 LEDs from 5V supply. BIT3269 is built-in 36V power switch with current mode control and provides fast response. An internal 650mA current limitation can provide the protection of internal switch. High operation frequency (1.2MHz), BIT3269 can reduce the inductor size and capacitor. All the functions are combined in a small SOT23-6 package.
