Ceratrans Driver for LCD Backlight

DIT8545 is an advanced LCD backlight inverter con-

trol IC based on the piezo-ceramic transformer. The

new control scheme employing the variable fr e-

quency and duty control achieves the very high effi-

ciency over 90%. In this control scheme, the soft

start and zero voltage switching functions are aut o-

matically obtained. DIT8545 can realize the CCFL

backlight inverter with small size and low cost.
