DC DC Converters

DC-DC converters are power supply systems designed to convert direct current from one voltage level to another. The most common conversion is from a higher voltage to a lower voltage, used in most electronic applications. A very popular DC-DC converter used today in many domestic and commercial electronic devices is the NME2415DC.

NME2415DC Application Field

The NME2415DC is a DC-DC converter with features of low heat generation, high efficiency and wide range of input voltages. This makes it suitable for use in a variety of different applications. Some of the more common applications are:

• Alternative Energy Systems - Solar, wind, water turbines and micro-hydropower systems that require DC to DC conversions.
• Industrial Automation - Factory automation systems require DC power for automation control.
• Telecommunication and Security Systems - These systems mostly run on high quality DC power.
• Military and Aerospace Electronics - Great care must be taken when distributing DC power in military and aerospace electronic systems.
• Test Equipment - Many test and diagnostic devices require DC power come with NME2415DC already integrated.

NME2415DC Working Principle

The NME2415DC is a DC-DC converter that uses a linear regulator-based design to convert higher voltage of DC electricity to a lower voltage, usually set by the user. This design provides a better and more stable output with less heat produced.

The NME2415DC uses a metal oxide semiconductor field effect transistor (MOSFET) for the main regulator. The MOSFET is attached to a voltage controller and a power protection unit. When an input voltage is entered which exceeds the programmed output voltage of the unit, the MOSFET regulates the current and will keep the output voltage at the programmed setting.

The voltage controller chip serves two purposes. Firstly, it helps to filter noise and disturbances from the input voltage before it enters the power protection unit. Secondly, it provides protection for the unit, limiting the maximum output voltage and current. The power protection unit is a set of two power diodes and an N-channel MOSFET used for rectification and inrush current control.

The NME2415DC is also equipped with short circuit protection, overload protection, over voltage protection, over temperature protection and under voltage protection. These features will help to keep the unit functional and safe from overload events. Plus, with a maximum input voltage of 28 volts and output current of 27.7 amps, the NME2415DC is a journeyman of power regulation.
