REC5-0505SRW/H4/A

DC-DC converters are essential components in power electronics, especially in the input side of electronic systems. The REC5-0505SRW/H4/A is an interesting example of DC-DC converters, which combines a wide input range with a low profile, wide temperature range, and high efficiency.

The REC5-0505SRW/H4/A is a 5W DC-DC converter suitable for 12 V to 48 V input. It is designed with surface mount technology and with an encapsulated plastic package. It comes with complete built-in EMI filter, making it suitable for use in a wide range of applications. It has a high efficiency up to 89%, and an operating temperature range from -40°C to 85°C.

The REC5-0505SRW/H4/A can be used in many applications in the field of power electronics, such as automotive, avionics, aerospace, medical, and industrial systems. It can be used to power electronic components such as-microprocessors, sensors, and other digital apparatuses. The converter is also suitable for applications that require low profile and high efficiency in harsh conditions.

The working principle of the REC5-0505SRW/H4/A is based on the use of a single inductor to transfer power from input to output. A buck converter is a type of DC-DC converter with an output voltage that is lower than its input voltage. In this type of converter, the input voltage is stepped down by an internal buck converter topology. The buck converter uses a switch to alter the voltage level between the input and output stages. The switch can be either a conventional bipolar junction transistor (BJT) or a more recent IGBT.

The buck converter of the REC5-0505SRW/H4/A integrates an input stage, a driver stage, a power stage, and a control stage, making it one of the most advanced solutions for DC-DC converters. This converter also benefits from the integration of a trans-impedance (input) stage buffer, which helps to protect against wide input voltage variations. It also offers current-mode controlled solution for high-efficiency performance and an adjustable soft-start for improved control.

Apart from these features, the REC5-0505SRW/H4/A also offers an excellent short-circuit and over-current protection, as well as thermal shutdown and over-temperature protection. Furthermore, this DC-DC converter provides a very wide operating temperature range, which makes it suitable for use in harsh conditions. With all these features, the REC5-0505SRW/H4/A provides a very high level of performance and is suitable for a variety of applications.
