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 fre-
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 auto-
matically obtained. DIT8545 can realize the CCFL
backlight inverter with small size and low cost.
