The REC3-2409DRWZ/H2/A/SMD-R is an advanced switch-mode power regulator that incorporates a number of features to improve overall efficiency and reliability. It uses an internal Current Mode control circuit, which allows for high-performance regulation over a wide load range. Furthermore, the converter features synchronous rectification, soft-start, external voltage and current monitoring, over-voltage protection and thermal protection for complete and optimized operation. It also has an adjustable current-limit to improve system safety and reliability.

The working principle of the REC3-2409DRWZ/H2/A/SMD-R converter is based on its power-conversion circuitry that consists of the main converter and the voltage regulator. The main converter consists of a transformer with an energy-storage element, a diode bridge rectifier and a switching transistor. The transformer increases or decreases the input voltage and the bridge rectifier converts the AC voltage into a DC voltage. The switching transistor then alternately switches on and off to regulate the output current.

The voltage regulator consists of an operational amplifier, an error amplifier and a reference voltage source, which work together to maintain a constant output voltage. The voltage regulator’s error amplifier compares the output voltage with its reference voltage. When the output voltage deviates from the set point, the error amplifier signals the switching transistor to adjust the output voltage. The operational amplifier adjusts the switching frequency to maintain constant output voltage.

Overall, the REC3-2409DRWZ/H2/A/SMD-R DC DC converter is a versatile component, capable of providing up to 8 A of power with high efficiency and excellent temperature operation. It is suitable for a variety of applications and is optimized for improved system efficiency and reliability.Its working principle is based on a power-conversion circuit with a transformer, diode bridge rectifier, switching transistor, operational amplifier, error amplifier and a reference voltage source for keeping the output voltage stable.
