DC-DC converters are commonly used to convert a DC voltage from one level to another. REC3-1205DRW/H/B is a tiny buck DC-DC converter module designed for cost-sensitive and space-sensitive application. This converter has high efficiency over a wide input voltage and very low no-load power consumption. It is also RoHS compliant and packed with one piece of FR4 substrate.

REC3-1205DRW/H/B has multiple application fields, such as, point-of-load power sources, computer motherboards, automotive electronics, industrial control systems, embedded systems, telecommunications, gaming consoles, etc. This module can deliver a max output power up to 25W with a 4:1 wide input voltage range of 6.5V to 24VDC. It has an ultra-wide output voltage adjustable from 0.8V to 18V and is suitable for industrial and commercial applications.

This converter also features very tight regulation and offer fast transient response to support all kinds of loads. At the same time, the module complies with demanding EMI requirements and meets the requirements of Quasi-Resonant type, IEC61000-3-2 harmonic current limitation and efficiency up to 93.2%. The device includes an internal synchronous rectifier, which reduces external losses and thus improves the efficiency, reliability and thermal dissipation.

The working principle of REC3-1205DRW/H/B is based on the buck converter, which is a straightforward topology for DC-DC voltage conversion. The converter module includes two main winding which are connected in series or parallel, depending on the application requirements. An inductor is then used to store electrical energy, which is released to the output end of the converter in form of a DC voltage. The inductor is driven by an internal power switch and is coupled to the output via a diode, which allows current to pass only in one direction.In addition, the module also has integrated protection features such as thermal protection, short circuit protection and over-voltage protection. The module is capable of maintaining a very high efficiency throughout a wide range of operating conditions. Furthermore, the module is applicable for operating temperatures between -40℃ to 85℃ making it suitable for a wide range of environments.
