With it, electrical conduction, conversion and switch can be completed with no wear of components, good reliability and longevity, low-voltage power conversion and so on.

Working Principle

In its most basic form, DC-DC converter is an electronic circuit or electromechanical device designed to change an input DC voltage to a different DC voltage. The most common DC-DC converters available are step-up, buck, and buck-boost converters. The REC5-053.3SRW/H6/C/M is a buck-boost.()

Buck-boost converters are typically used when the input voltage is either below or above (or both) the desired output voltage. When the input voltage is lower than the output voltage, the converter is said to be in buck mode, increasing the voltage. When the input voltage is higher than the desired voltage, the converter is in boost mode, decreasing the voltage and increasing the current.

The output voltage of the REC5-053.3SRW/H6/C/M is regulated by a Pulse Width Modulation (PWM) controller or a Pulse Frequency Modulation (PFM) regulator as it has an adjustable output voltage, usually in form of a voltage divider. The regulator then adjusts the power to maintain the desired output.

The REC5-053.3SRW/H6/C/M has two L-C filters which give it excellent line and load regulation. It has high efficiency, and can handle a maximum power of 5W, with the operating temperature ranging from -25°C to 85°C. Moreover, it has 2000V DC isolated working efficiency, making it safe and reliable.
