I have an existing design that uses the TPS68000 and two IR F7303's, I would like to use this driver circuitry to power a string of LED's instead of the CCFL bulb which came with the displays I used and cannot get replacements for. What should I use for the current sense and voltage sense resistors to get this working without the step-up transformer? Any pointers on how to trick the driver into doing my bidding? Thanks!
