Hi everyone,
I am trying to build a buck converter using an LM2675-ADJ. I am trying to convert from 12v to 6v. I followed the instructions in the LM2675 datasheet. The problem is I am getting only a few mV on the output and the LM2675 gets super hot fast. I have rebuilt this circuit 5 times on different boards and different layouts. I made sure my soldering is good. I just can't diagnose what I am doing wrong any help would be appreciated.
I am using the following parts:
1000ohm resistor
3900ohm resistor
1n5822 Schottky diode
100uH Inductor
2200uF Electrolytic Capacitor
1000uF Electrolytic Capacitor
