Working Principle

The REC3-4805SRWZ/H4/A/SMD DC-DC converter operates based on a closed loop step down switching DC/DC conversion principle. The basic conversion follows three steps:

1. Input rectification - The converter takes in a DC input voltage and rectifies it using a diode bridge rectifier.
2. Conversion - The rectified DC voltage is then converted to a lower voltage using a power MOSFET switch.
3. Smoother - The output voltage is then smoothed and regulated using an integrated voltage regulator.

The working process can be represented as follows:

The power MOSFET switch is used to control the converter\'s input current and voltage, while the voltage regulator is responsible for the output voltage and current regulation. The MOSFET also provides the necessary isolation between the input and output stages.

The REC3-4805SRWZ/H4/A/SMD converter is a highly reliable and efficient solution for a wide variety of applications. Its wide input voltage range, excellent temperature range and integrated protection features make it an ideal choice for many devices.
