Working Principle

The REC5-4809DRWZ/H6/C/SMD DC-DC converter is a step down converter which reduces the input voltage to a specific level. The converter achieves this by using two power transistors as switches, along with an inductor, four capacitors, and a control circuit. The input voltage is rectified and smoothed by the four capacitors before being applied to the control circuit. The control circuit then uses the step down switching process to determine the amount of power to be delivered to the inductor. The inductor stores the power before releasing it to the output capacitor, thus reducing the output voltage.

The output voltage is regulated by adjusting the duty cycle of the two switches, which is done by the control circuit based on an internal reference voltage. The output voltage will stay within the specified range as long as the input voltage stays within the range of the converter. If the input voltage is too low or too high, the control circuit will protect the components from damage by automatically shutting off the power to the inductor. This makes the converter extremely reliable, as it is designed to protect itself and the connected components from damage.
