BIT3102B

BIT3102B Low Cost PWM CCFL Controller General Description To aim at the Cold Cathode Fluorescent Lamp (CCFL) applications, BIT3102B integrates all functions required in a single 14-pin chip. The chip provides a fully functioning PWM control circuit with a true load feedback protection. By setting the required time for starting up the load, the fault detection condition can be detected after start-up period. The output load control can be done through a PWM feedback loop. CMOS process reduces the operating current (1mA typical) and NMOS output driving capability enhances the system efficiency.
