hi,
Actually this circuit contains DC-DC Converters, 4 line LCD, Controller, Op amp, Opto coupler and FET
Application:
I am getting External analog input, this will read by ADC, based on that input i need to drive the FET and also dispaly the input volt, Duty cycle and other details . Thats the major thing in this project otherwise nothing in the schematic... this is used inject the Fuel in industry
It carries maximum of 5A from DC-DC.
Kindly give me an idea about the design...
