Introduction
DC-DC converters are electrical devices used to convert direct current (DC) voltage from one level to another. Generally speaking, they are used in applications to modify the voltage of a power source in order for it to be compatible with a given device. Direct current converters come in a range of different forms, from step-up to boost, boost-buck, buck, buck-boost, forward, flyback, cuk, push-pull, half-bridge, and full-bridge options.The REC3-1212DRW/H2/A/M/SMD/CTRL is an example of a buck converter commonly used for DC-DC conversion applications. It operates on a single inductor, dual diode, two switching poles (High-side + and Low-side –), as well as two resistors to floor and ceiling.Application Field of the REC3-1212DRW/H2/A/M/SMD/CTRL
The REC3-1212DRW/H2/A/M/SMD/CTRL is a versatile converter commonly used in a variety of different applications. It is suitable for general or high power applications in telecom, industrial, and automotive industries, and boasts an input up to 400VDC and output current up to 10A. Additionally, it offers a wide input range of up to 3-12V, an adjustable output voltage, efficiency up to 95%, and a compact size. Common uses of this converter include telecom, industrial, computer, automotive, and telecom equipment.Working Principle of the REC3-1212DRW/H2/A/M/SMD/CTRL
The REC3-1212DRW/H2/A/M/SMD/CTRL works on a buck operating principle, meaning that the input voltage is reduced relative to the output voltage. The converter operates as follows: the high-side MOSFET and low-side diode are switched on and the inductor then begins to store energy. When the switch is off, the energy stored in the inductor is then released and the voltage is reduced. This process continues in a cyclic fashion as long as the converter is in operation. An additional advantage of this converter is that it requires no complicated control circuit, allowing it to maintain a high level of stability and reliability.Conclusion
The REC3-1212DRW/H2/A/M/SMD/CTRL is a versatile buck converter commonly used for DC-DC applications. With an input up to 400VDC and output current up to 10A, the converter is suitable for applications in telecom, industrial, and automotive industries. This converter operates on a single inductor, dual diode, two switching poles, and two resistors to floor and ceiling and helps maintain a high level of stability and reliability.
