DC-DC converters are valuable components that provide a clean, transformed power source for DC circuit applications. This article will discuss the application field and working principle of the REC5-4805DRW/H2/A/M/SMD/CTRL-R DC-DC converter.

The REC5-4805DRW/H2/A/M/SMD/CTRL-R converter is a high-efficiency, low-power-consumption, small-size Isolated DC-DC Converter that provides a regulated output voltage to a voltage source, such as a low-voltage photovoltaic, a single cell lithium-ion battery or a larger battery pack. Its 56.2kHz fixed frequency PWM control allows for superior EMI noise characteristics making it suitable for applications in noise-sensitive areas. Its high power density (5.25W/cm3) means that its power capability to volume ratio is the highest available in the market, making it ideal for applications where space is a premium.

REC5-4805DRW/H2/A/M/SMD/CTRL-R converter is designed to be a general building block power solution for automotive, industrial and consumer applications, such as motor controls, automotive systems, medical systems and consumer electronics. This converter can output power from 3.3Vdc to 20Vdc output and efficiency up to 87%. Load regulation and line regulation of the output voltage can be up to 0.4% and 0.2(max) respectively. Short-circuit protection and high temperature protection are also built in.

The REC5-4805DRW/H2/A/M/SMD/CTRL-R converter is an adjustable,Isolated DC-DC converter control circuitry makes it suitable for multichannel, multipurpose functions requiring different input/output voltages and currents. It is contained in a foldable housing package that allows the converter to be easily mounted in areas where space is very limited, such as automotive interior panels or mobile phones. It is designed to be highly reliable, with no possibility of mechanical problems due to additional external components.

The working principle of the REC5-4805DRW/H2/A/M/SMD/CTRL-R converter is based on the pulse-width modulation (PWM) technique. The PWM control circuitry allows the input voltage to be converted and controlled in a sinusoidal waveform. A high-voltage side transformer and a low-voltage side printed circuit board (PCB) form a voltage dividing capacitor-filter-inductor structure that together act as a voltage-dividing load. An auxiliary winding is used to control the output voltage. The primary and auxiliary winding currents are monitored and regulated to maintain a constant output voltage.

The REC5-4805DRW/H2/A/M/SMD/CTRL-R converter is a reliable and efficient Isolated DC-DC converter that integrates a power transistor and high-temperature components that provide a stable output voltage, as well as short-circuit and over temperature protection. Its PWM control technique ensures that the converter is capable of providing significantly improved power conversion efficiency, reducing the power dissipation and maximising the overall system performance.

REC5-4805DRW/H2/A/M/SMD/CTRL-R converter is the ideal choice for efficient power transfer in automotive, industrial and consumer electronics applications. Its size and power density make it suitable for applications where space is limited, yet its PWM control circuitry allows for improved performance and EMI noise characteristics making it suitable for noise-sensitive applications.
