DC DC Converters

DC-DC converters are an important element of power systems, providing power conversion between two independent sources. In particular, DC DC converters can differentiate between different supply voltage levels, as well as tailor power requirements for different loads. They are often used to match load power requirements to the power available from the source. The NMH1215DC is a member of the DC DC converter family and is widely used in power systems.

NMH1215DC Application Field

The NMH1215DC is used in many power systems because of its high density design and efficient conversion. It is suitable for use in either a high-current application or a low-current application, such as battery-powered systems, lighting circuits, and automotive electronic systems. This converter is capable of supplying continuous output current of up to 15 Amps and offers a wide input voltage range of 4.5 V to 28 V DC.

Working Principle

The NMH1215DC features a unique resonant half-bridge architecture with an integrated transformer-based converter, which helps achieve higher efficiency than other DC DC converters. This converter utilizes a fixed off time, variable frequency, resonant control scheme to provide high efficiency over the entire input voltage range. When the input voltage is low (below 8 V), the converter automatically switches to continuous conduction mode to further improve efficiency. The NMH1215DC has a wide range of output voltage options, which are user-selectable using an external resistor. The soft-start function prevents input surge current and output overshoot when powering up, while the frequency modulation feature helps protect against voltage spikes and short-circuit conditions. In addition, the circuit features a thermal Shutdown protection and continuous automatic skip cycles to reduce temperature and improve efficiency.

Benefits

The NMH1215DC promises a number of advantages for electronic system applications. By utilizing the advanced half-bridge architecture, this converter is able to provide higher efficiency than the conventional buck or boost DC DC converter. This improved efficiency is most noticeable in applications requiring high-output currents, such as those used in automotive systems, where the converter is capable of sustaining high current levels without compromising performance.The converter\'s wide input voltage range allows it to be used in a variety of applications, including battery-powered systems, cellular phones, medical instrumentation, and lighting circuits. In addition, the NMH1215DC is very compact, making it suitable for use in space-constrained applications. The built-in protection circuitry also offers increased reliability in harsh environments.To sum up, the high efficiency and wide input voltage range of the NMH1215DC make it an ideal choice for power electronic systems. Its robust design and wide range of features promise reliable operation, even in the most demanding situations.
