BIT3102B
Low Cost PWM CCFL Controller
General Description:
To aim at the Cold Cathode Fluorescent Lamp (CCFL)
applications, the BIT3102B integrated all functions
required in a single 14 pin chip. The chip provides a
fully functioned PWM control circuit with a true load
feedback protection. By setting the required time for start
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
Features:
PWM Modulation
Open Lamp Protection
Internal UVLO (Under Voltage Lock Out) function
Dimming Control
CMOS Totem Pole output
NMOS output driving
