Hi, I currently trying to troubleshoot this device. At the moment I am able to get 0.8 to 1.8 volts with the potentiometer which is not an issue. The current on the other hand is the issue. The current maxes out at 4amps and I need it to be in the 8-10 amp range. The current is following the voltage so 1.8v = 4a, 1.6 = 3.8a etc....
I have it set up such that:
Pin 1+2 = Vout -
Pin 3+4 = Vout +
Pin 5+6 = Vin w/ 560uF metal and 22uF metal capacitor in parallel (I'm using a 12V/3A wall wart as a Vsupply)
Pin 7 = I initially had it connected to Pin 4, but removed it during troubleshooting w/ no resolve
Pin 8 = I have a 10k rotary potentiometer connected to GND
Pin 9 = I had this pin connected to Pin 6, but removed it while troubleshooting w/ no resolve
Pin 10+11: GND
Pin 12: I initially had this connected as an on/off, but removed it during troubleshooting w/ no resolve.
I noticed the emphasis on using a 22uF ceramic capacitor in the schematic, but it's all I have. I wouldn't imagine this would be the root of my issue.
I'm puzzled why it's maxing at 4 amps when the device is capable of 16 amps.
Thank you.
