I am using UCD3138ACCEVM149 (Control Card) with UCD3138ALLCEVM150 (Daughter Card).
I changed capasitances,transformers and secondary side FET's on EVM150( Daughter card) in order to achieve my desired output levels.
After the hardware changes that I made , I tested the board (EVM150) with two external PWM signals.
I reached my desired output levels so Im certain that there is nothing wrong with my hardware setup.
The problem is when Im using "Fusion Digital Power Studıo" to tune UCD3138A chip on EVM149( Control Card) , I am not able to reach any output level which is higher than 18Vdc.
EVM150(Daughter Card) comes with components which have 16Vdc ratings. So I suspect there is an extra protection which supressing the EVM.
I changed several parameters both in Firmware ( with using CCS) and Fusion Digital Power Studıo but nothing solved my problem.
What changes should I make in firmware to have higher voltage outputs than 18 V ?
