Hi, I want to convert 12V to 9V 2.5A constant current.
I am using FL7760 IC for the same.
Please find the attached circuit.
When I test it on PCB and gave 12V input to the circuit from power supply. I got same 12V at output without load when I measure using multimeter. It's does not buck. Can you please guide me, why? Also, I have just add capacitor and ground it to the pin Vcc (as I found in datasheet). I didnt gave 5V supply.
