DC DC Converters

REC3-4805SRWZ/H6/A/SMD-R is an 8-pin standard DC/DC converter module, which features an input voltage range of 2.7V to 5.5V, and an output voltage of 5V. It is specifically designed for mobile applications such as smart phones, tablets, and portable devices.

DC/DC converter modules are used to convert one DC voltage to another DC voltage. The input / output are either AC or DC. They consist of a regulated power supply, a voltage regulator and an inductor. The main advantage of DC/DC converters is providing an efficient and cost effective way to convert different voltages, a task traditionally done with bulky and resource intensive transformers.

REC3-4805SRWZ/H6/A/SMD-R Application Field and Working Principle

The REC3-4805SRWZ/H6/A/SMD-R is specially designed for mobile applications. Its wide input voltage range and 5V output makes it ideal for powering and charging mobile devices such as phones, tablets, and portable media players. Its small size makes it a great choice when space inside the device is limited.

As for its working principle, the REC3-4805SRWZ/H6/A/SMD-R module operates in what is known as buck-boost mode. In this mode, the module operating frequency remains constant regardless of the input voltage, which improves efficiency and makes the module more reliable. The input is rectified and then converted to a higher voltage which is then switched through an inductor and then regulated to the final output voltage.

The switching affects the impedance of the inductor, increasing and decreasing the current through it. This change of current generates an electromotive force that counteracts any changes on the voltage and provides a smooth output voltage. The REC3-4805SRWZ/H6/A/SMD-R module has protection circuits in place to protect the module from over voltage, over current and over temperature. The module also has short circuit protection and features a remote on/off control.

Overall, the REC3-4805SRWZ/H6/A/SMD-R module is a reliable and efficient DC/DC converter for mobile applications, offering features such as wide input voltage range, 5V output, buck-boost mode and short circuit protection. It is the perfect choice for powering and charging mobile devices.
