com DIT8545 Ceratrans Driver for LCD Backlight DESCRIPTIONS DIT8545 is an advanced LCD backlight inverter control IC based on the piezo-ceramic transformer.
The new control scheme employing the variable fr equency and duty control achieves the very high efficiency over 90%.
In this control scheme, the soft start and zero voltage switching functions are aut omatically obtained.
DIT8545 can realize the CCFL backlight inverter with small size and low cost.
