DC DC Converters

The MGJ2D122005SC is a high power DC-DC converter designed for high-performance applications in the telecom and industrial markets. It has excellent thermal efficiency, high power density, outstanding performance, and is highly reliable. The MGJ2D122005SC offers low output voltage ripple, and supports high system voltage.

Applications

The MGJ2D122005SC can be used in mobile radios, base station power supply, industrial fieldbus power supplies, automotive applications, UHF radios, HVAC and other power systems applications. This power regulator is mainly used in distributed power architectures, and in multi-level power systems.

Working Principle

MGJ2D122005SC works by controlling the current of an inductor to regulate the output voltage. The inductor provides stepdown current conversion and the regulator provides the feedback loop to keep the output voltage stable under different load conditions. The circuit diagram of the MGJ2D122005SC includes an input terminal, an output terminal, an inductor, a capacitor, and a feedback loop. The input terminal takes DC voltage from a power supply and transfers it to the output terminal that provides the regulated voltage. The inductor passes a current spike when the input voltage is applied and then passes the current from the input to the output. The capacitor stores the current spike and helps regulate the output voltage. The feedback loop senses the output voltage and delivers an analog output signal to the internal error amplifier, which then signals the driver circuit to heat up the output switch and regulate the output voltage.
