5V Highly-Integrated, Digital Dimming CCFL Inverter Module
PRELIMINARY DATASHEET
This module has been designed to operate over a wide range of input and output conditions. However, best efficiency and performance
will be obtained if the module is operated under the condition listed in the ‘R.C.’ column. Min. and Max. columns indicate values
beyond which the inverter, although operational, will not function optimally.
