DC-DC converters, commonly known as switching power supplies, are power conversion devices used to modify the voltage level of the power supply in order to better meet the requirements of a particular application. R0.25D12-3.315/HP is a type of DC-DC converter which is used in various industries including automotive, military and aerospace applications. This article seeks to explore the application fields and working principle of this particular type of converter.

Applications

R0.25D12-3.315/HP is a low power, isolated, switched mode DC-DC convertible that provides unregulated, 9-16V, 2.7A output power with built-in filtering and current limiting. It is suitable for use in numerous applications, including but not limited to: automotive engine control, police and fire radios, medical diagnostic equipment, computers and communication systems, instrumentation, industrial products and general purpose power supplies. In addition, this converter is also used in military and aerospace applications such as missile guidance and aircraft navigation systems.

Working Principle

The R0.25D12-3.315/HP converter works on the principle of pulse-width modulation. This type of converter converts the input DC power by a switching action regulated by a timing signal, thus creating a pulsed output voltage. The timing signal is controlled by two separate blocks: a controller block and a power switch block. The power switch block consists of power transistors, capacitors, inductors, diodes, resistors and other components which regulates the power switch. The controller block consists of an integrated circuit, timing elements and an output filter which work together to produce the desired output signal. The circuitry inside the converter constantly monitors current, voltage and temperature. If any of these parameters reach an unacceptable level, the converter will enter a protection mode and shut off the power supply.

Conclusion

The R0.25D12-3.315/HP DC DC converter is a low power, isolated, switched mode DC-DC convertible with numerous applications in various industries. It employs the principle of pulse-width modulation to convert the input DC power and the integrated circuitry ensures that the output signal remains at an acceptable level. As a result, this type of converter has become a popular choice for commercial and industrial applications.
