Hi,
I am facing problem with my circuit which is designed with the help of LTC3895. My requirement for the output and input are as follows:
Input: 25 to 140V
Output : 20V 3Amp ( There are 3 parallel output slot each giving out 20V @ 1 ampere)
Even added a p-mos to give reverse polarity protection.
As per the stimulation it is working fine but when I experiment it on PCB circuit board the output seem low or sometimes there is no output. Please help me out here.
I have attached the schematic design and the voltage output graph for the same.
Note: At present diagram there is no load connected at the outputs but there will be 15V load in series to 3ohm resistor.
