​ REC3-4812DRWZ/H4/C/SMD-R is a type of DC-DC converters. It has different applications and working principles. This article will discuss the different application fields and working principles of this device.

Application Field

​ REC3-4812DRWZ/H4/C/SMD-R is mainly used in power conversion from input DC voltage to output DC voltage at different levels. It is wide used in many applications, such as motor controllers, industrial power supply, automotive electronics, aircraft avionics, military power equipment, telecom applications, medical instrument and robotics.

Working Principle

​ REC3-4812DRWZ/H4/C/SMD-R has a conversion efficiency over 85%, making it one of the most efficient power devices in the industry. It is based on a synchronous buck topology, which means it has two main stages – the main RT and the secondary RT. The primary RT is responsible for controlling the output voltage of the device, while the secondary RT is responsible for current regulation. The two stages operate together under close feedback control.​ When the device is operating, the primary RT senses the output DC voltage and adjusts the switching frequency to maintain the desired voltage. The secondary RT senses the current load and adjusts the switching on-time to maintain the desired current load. The two stage operation ensures a high conversion efficiency and stable output even under varying load.

Conclusion

​ In conclusion, REC3-4812DRWZ/H4/C/SMD-R is a DC-DC converter designed for a range of different applications. It has a high conversion efficiency and is based on a synchronous buck topology. It has two main stages – the primary RT and the secondary RT – which work together to maintain a stable output voltage and current.
