It is also RoHS compliant, making it a cost-effective and reliable solution for power conversion applications.

The REC5-483.3SRW/H/B/SMD DC-DC converter works by using a buck-boost topology. This topology uses two transistors or MOSFETs, a high-side and low-side transistor, to switch the current flow between two input or output terminals. The converter utilizes pulse-width modulator (PWM) control to regulate the current flow within the circuit. With PWM control, the output voltage is regulated by comparing the feedback signal from the output voltage to a reference voltage. During PWM control, the converter rapidly turns on and off the output current, allowing for a smooth conversion with minimal distortions.

The REC5-483.3SRW/H/B/SMD DC-DC converter is an excellent choice for DC power conversion applications. It has a wide input voltage range, high efficiency, and high power density, making it suitable for a variety of industrial, medical, networking, telecom, and instrumentation applications. With its excellent load regulation, transient response, and protection features, this converter is a reliable and cost-effective solution.
