DC-DC converters are a type of power electronics device designed to alter the voltage, current, or both of a power supply in order to make it more suitable for a given application. The REC5-2409DRW/H2/C/SMD, (hereafter referred to as the REC5) is a type of DC-DC converter designed to convert a 24V input into a 5V output. It is well suited for industrial, automotive, and telecom applications.The REC5 utilizes a peak-current-mode controlled switching regulator with a constant frequency operation that helps to minimize the size and complexity of the circuit. This switching regulator attains a high level of efficiency and accuracy even at very low or no-load conditions and in-rush currents thanks to its internal MOSFET power switch.The peak current mode control also reduces unwanted noise and electromagnetic interference that can potentially damage sensitive components. Additionally, the REC5 is equipped with a covered terminal pin to help protect it from heat and other environmental elements.The working principle of the REC5 follows that of a typical peak current mode controlled switching regulator circuit. First, the power supply is connected to the input of the REC5 via a full-wave bridge rectifier. The rectified AC voltage is then filtered to produce a DC voltage that can be regulated.Next, the voltage is applied to two switching MOSFETs which are controlled by the peak current mode controller. The controller drives the MOSFETS such that a regulated voltage across the output is maintained.As the load on the output varies, the controller adjusts the duty-cycle of the switching MOSFETs accordingly, allowing a near-constant output voltage to be maintained. In order to minimize the current ripple, a small capacitor can be connected at the output.The REC5 is well suited for applications that need to convert a 24V DC voltage to a 5V DC voltage. Typical applications for this device include industrial, automotive, and telecom systems. It provides a high level of efficiency and stability by utilizing peak current mode control, and is also resistant to environmental elements due to its covered terminal.
