DC DC Converters

REC3-4805SRWZ/H/B/SMD-R application field and working principle

DC-DC converters are widely used in various electrical systems. As their name suggests, they convert direct current (DC) into regulated direct current (DC) with adjustable current, voltage, timing, and power. The REC3-4805SRWZ/H/B/SMD-R is a high efficiency and low noise DC-DC converter drivers developed for automotive applications, which can be used to provide a stable output voltage for several control systems.

The REC3-4805 SRWZ/H/B/SMD-R converter is a new generation of highly efficient DC-DC converters, designed to replace outdated magnetic cores and transformers. It has an integrated circuit similar to an operational amplifier, which can process input signals from the car\'s ECU via a switching mode and then control the output voltage of the converter to the desired level. It also has a high conversion efficiency, small size, and low EMI generation which makes it suitable for automotive applications.

The REC3-4805SRWZ/H/B/SMD-R converter has two main working principles, buck-boost and buck-buck. In buck-boost mode, the converter accepts a variable input voltage and uses its built-in regulators to produce an output voltage that is higher or lower than the input voltage. This allows the converter to be used in applications where the supply voltage requirements vary, such as automotive climate control systems, where the input voltage may vary between 6 and 14 volts.

In buck-buck mode, the converter takes a fixed input voltage and regulates it to an adjustable output voltage. This allows the converter to be used in applications such as engine management systems, where the output voltage must be accurately regulated and may not vary over a wide range.

The REC3-4805SRWZ/H/B/SMD-R also has built-in protection features such as thermal shutdown, overvoltage protection, and short circuit protection. These protection features ensure that the converter is not damaged in the event of a fault or excessive current or voltage.

Overall, the REC3-4805SRWZ/H/B/SMD-R is an excellent choice for various automotive control systems due to its high efficiency, small size, low EMI generation, and advanced protection features. It is perfect for applications such as engine control systems, climate control systems, and lighting systems, where it can provide a stable output voltage for optimum system performance.
