DC DC Converters

REC3-0505SRW/H6/A/SMD-R is a new line of DC DC converters from the REC3 Series. It is a flyback topology converter with a maximum power output of 5 Watts. This DC DC converter utilizes a secondary winding current sense and primary winding voltage sense to offer a total system efficiency of up to 88%. It is designed to supply the necessary power for various applications such as medical devices, industrial control systems, and general-purpose power supplies.

Application Field

The REC3-0505SRW/H6/A/SMD-R converter can be used in a variety of applications, both indoor and outdoor. Its compact size makes it an ideal choice for applications that require high efficiency. It can be used in medical devices, industrial control systems, and general-purpose power supplies. It is also suitable for other high-power applications such as plug-in LED lights, outdoor lighting, electronic displays, and cabling systems.

Working Principle

The REC3-0505SRW/H6/A/SMD-R converter uses a Flyback topology to generate an isolated output voltage. The operation is based on the principle of magnetic coupling. It has a primary winding and a secondary winding which are wound on a single ferrite core. The primary winding is connected to the input voltage source and the secondary winding is connected to the load. When a voltage is applied across the primary winding, it generates a magnetic flux which induces a voltage across the secondary winding. This voltage is then rectified and filtered to provide a DC output voltage. The power output of the converter is determined by the number of turns in the primary winding and the amount of flux generated within the core.

The isolator coil suppresses any noise generated from the converter and reduces the flow of current in the secondary winding. The current sense coil is used to monitor the current flowing in the secondary winding. This allows the converter to operate in constant current mode.

The REC3-0505SRW/H6/A/SMD-R converter also has a built-in over-current protection. This prevents the converter from drawing too much current and potentially causing a short-circuit. It also has an over-temperature protection which will switch off the converter if it reaches a certain temperature.

Conclusion

The REC3-0505SRW/H6/A/SMD-R converter is a highly efficient DC DC converter that can be used in a variety of applications. It has a built-in current sense feature which allows it to operate in constant current mode and an over-current protection which prevents the converter from drawing too much current. It is designed to be used in medical devices, industrial control systems, and general-purpose power supplies.
