This is a multi-output power supply based on LM2576HV-ADJ and LM317 IC. The power supply provides 3 outputs with input supply up to 55V DC. Output (O1) is adjustable up to 24V DC and load current of 2A, Output (O2) is adjustable to 1.2V-24V with load current up to 500mA and Output (O3) adjustable 1.2V-24V @ 500mA. High voltage LM2576HV-ADJ converts 55V in 24V DC. This output is adjustable but advisable to set the output to 24V DC with help of Trimmer Pot PR1.
Note: Keep PR1 at 50% before power up the project and set the Output-1 24V DC, then O2 and O3 can be set using P1 and P2.
