DC-DC Converters

DC-DC converters are used to convert direct current or a DC voltage from one level to another. DC-DC converters can also be used to convert AC from one frequency to another, or to change the voltage level of a DC voltage. They are found in many applications such as power supplies, electric motors, laptops, and other portable electronic devices. DC-DC converters may be used in various types of applications, including consumer electronics, automotive, medical, avionics, telecommunications, and industrial applications.

Among the wide range of DC-DC converters, the REM6-1205S/A is a high performance non-isolated point of load DC-DC converter offered by RECOM Power. This converter is designed for a wide input range of 4.5 to 14VDC and provides a highly regulated output of 5VDC. It offers a high efficiency of up to 95% and operates with a low ripple and noise of 40mVp-p. Due to its small size, it is suitable for space-sensitive applications. It has great features like remote on/off, output voltage trim, over current protection, and short-circuit protection.

Application Field

The REM6-1205S/A is suitable for applications that require a highly regulated and reliable 5V output such as networking, computer system applications, transportation applications, broadcasting and audio applications, medical instruments and diagnostic equipment, and measuring systems. It is especially suitable for space-sensitive applications. Its wide input voltage range allows it to be used in various applications where the input voltage may vary from 4.5 to 14VDC.

Working Principle

The REM6-1205S/A DC-DC converter uses a buck converter topology which consists of an inductor, a diode, a switching transistor, an error amplifier, and a control circuit. The duty cycle of the switch determines the output voltage. The error amplifier compares the output voltage with a reference voltage and generates an output voltage control signal. The control circuit then adjusts the duty cycle accordingly.

When the input voltage is higher than the output voltage, the inductor will store energy in an electric field as the switch passes current through it. When the switch is turned off, energy from the electric field will be released into the load. At the same time, the diode will prevent reverse-current. In this way, power is transferred from input to output.

The efficiency of the REM6-1205S/A DC-DC converter highly depends on input voltage, the output current, and the efficiency of the components used in the converter. With its high efficiency up to 95%, the REM6-1205S/A DC-DC converter is extremely reliable and efficient.

In summary, the REM6-1205S/A DC-DC converter is a high performance non-isolated point of load DC-DC converter, offering a wide input voltage range and a high efficiency up to 95%. It is suitable for applications that require a highly regulated and reliable 5V output. Its buck converter topology with an inductor, a diode, a switching transistor, an error amplifier, and a control circuit, allows power from input to output to be transferred. It is thus widely used in consumer electronics, automotive, medical, avionics, telecommunications, and industrial applications.
