DC DC converters are devices that convert direct current (DC) power from one voltage to another. The REC5-4815SRW/H/B/SMD is a step up/step down DC-DC converter designed for the telecommunications, computing, automotive and portable device market. It is a cost-effective solution suitable for applications requiring high efficiency and regulated voltage from a lithium ion battery.

The REC5-4815SRW/H/B/SMD is a buck-boost converter with a DC input voltage range of 4.5V to 65V and an output voltage range of 15V to 48V. It is capable of providing up to 15A of output current with a maximum efficiency of 95%. The converter offers several features, such as short circuit protection, over voltage protection, thermal protection, constant output voltage regulation and low standby current consumption.

The REC5-4815SRW/H/B/SMD is available in a small SOT-23 package and operates over an ambient temperature range of -40˚C to +85˚C. Its size and wide temperature range make it an ideal choice for applications where space is tight and temperature extreme.

The working principle of the REC5-4815SRW/H/B/SMD is to convert a higher DC voltage into a lower DC voltage with no AC component involved. It is based on a buck-boost topology, meaning that it switches between buck and boost mode depending on the input and output voltage. This makes it possible to step-up (boost) or step-down (buck) the input voltage as required. This converter utilizes switching technology, where transistors are switched on and off at high frequency, to regulate the output voltage and current.

The REC5-4815SRW/H/B/SMD has numerous applications, ranging from automotive electronics to communications and portable devices. It can be used to convert a continuous voltage, such as an automotive battery, into a regulated voltage to charge a device for an extended period of time. In mobile applications, it can be used to power consumer electronics and communication devices, such as MP3 players or cell phones, without having to use bulky transformers.

In conclusion, the REC5-4815SRW/H/B/SMD is a cost-effective step up/step down DC-DC converter, ideal for applications requiring a regulated voltage from a Li-Ion battery with a wide range of input and output voltage. Its small size and wide temperature range make it ideal for space-constrained applications. The converter works on a buck-boost topology, which allows for both buck and boost operations, making it suitable for any DC-DC conversion needs.
