DC-DC converters are widely applied in a range of industries for providing a wide range of power solutions, from controlling voltage and current levels, regulating the speed of electrical motors, to providing the correct DC voltage or current for a specific application. Among these, the MTU1D1209MC-R converter, manufactured by Traco, is a Power Supply Module with step up and step down output. This article will discuss the application fields and working principle of the MTU1D1209MC-R.

Application Field

The MTU1D1209MC-R converter is widely used in a range of applications including communications, industrial, medical, military, and electrical automotive applications. Owing to its step up and step down transfer ratio and output current, it is suitable for high-precision voltage and current regulation.

Working Principle

The MTU1D1209MC-R converter is based on the principle of buck-boost technology. This technology combines the buck and boost topologies into a single component, which allows it to produce both step up and step down outputs. It operates by continuously modifying and regularly switching the current and voltage proportions in order to switch between boost and buck operations.

When operating as a step up converter, it increases the voltage from an input source using the inductor and Rectifier Bridge Rectifier (RBR). The inductor stores energy on the way up and releases this energy as the voltage begins to decrease. This higher voltage is then regulated using a comparator and MOSFET switch. The output is then the boosted voltage, regulated by the comparator.

When operating as a step down converter, it reduces the voltage from an input source using the inductor and RBR. The inductor stores energy as the voltage begins to increase, and releases this energy as the voltage begins to decrease. This reduced voltage is then regulated using the comparator and MOSFET switch. The output is then the reduced voltage, regulated by the comparator.
