Working Principle

The REC5-4812DRWZ/H4/A/SMD/CTRL-R is a DC/DC converter that uses the buck (step-down) topology to convert input voltages of 5-48V into a 12V, 1.5A output. The device features a fixed-switch frequency of 300 KHz which allows for a fast transient response while also reducing EMI. The switching regulation ensures that the output voltage is accurately regulated over the entire input voltage range.

The device consists of a power transistor, an input/output filter, a control circuit, and a feedback loop with a feed-forward compensation network. When the device is powered up, the power transistor is turned on, allowing current to flow from the input to the output. This current is regulated by the internal control circuit and feedback loop. The input/output filter is used to smooth out any noise or ripple that may be present in the input or output voltage.

The feedback loop consists of a voltage regulator and a circuit that compares the output voltage to a reference voltage. If the input voltage is too low or the output voltage is too high, the power transistor is turned off, preventing overloading of the device. This regulation process is constantly repeating, ensuring that the output voltage is regulated over the entire input voltage range.

Overall, the REC5-4812DRWZ/H4/A/SMD/CTRL-R is a highly reliable device that offers a wide input range, high power density, low power consumption, and a fast transient response. Furthermore, the device features many protection features making it ideal for use in high-end computing, telecom, industrial, and automotive applications.
