I was debugging the MP1584 module, 5v regulator circuit in the PCB. I have attached my debug circuit below.

MP1584 debug circuit

I have completed my circuit in breadboard and PCB also, but I was connected to any load below 2A. It will produce the voltage drop and alternative output voltage.

Mp1584 specs : max 3A , i/p volt = 4.5v to 28v , my i/p volt = 12v

I need 5 V output and less than 2 A current. How can I achieve this?

    \$\begingroup\$ Did the input voltage to the regulator also drop? \$\endgroup\$ – Andy aka Sep 9 at 8:29
  • \$\begingroup\$ The schematic photo has very poor resolution but the components seem to be against suggested values for 5V operation. \$\endgroup\$ – Justme Sep 9 at 8:34
