The MK-MOD-1 Pro-Grade DC-DC Converter is a high-efficiency, universal 3-wire switching power supply module designed for rapid circuit repair, voltage regulation, and hardware prototyping. Driven by a UC3843AN PWM controller and isolated flyback architecture, this turnkey board easily replaces failed primary power stages in LED/LCD monitors, CRT TVs, and industrial electronics. Dual PC817 optocouplers provide precise voltage feedback across a safe galvanic isolation barrier, while dedicated current-sense resistors ensure active short-circuit and over-current protection.
