DC-DC converters are devices that take a source of direct current (DC) power, and convert it into a different form, either a higher or lower voltage. The IH2415S is a module type DC-DC converter manufactured by Isahaya Electronic Corporation and used in many industrial applications. This article will discuss the application field and working principle of the IH2415S.

The IH2415S is mainly used for DC voltage conversion and DC power supply. It supports coaxial DC input voltage from 12V to 48V, and it provides a rectified DC output voltage of 15V. This module is highly efficient with up to 94% efficiency under normal operation and up to 96% efficiency under light load conditions. It also offers an adjustable output current of up to 2.5A for powering components or motors. The module also offers overvoltage, overcurrent, undervoltage, and over-temperature protections to ensure its safe operation.

In terms of its working principle, the IH2415S DC-DC converter is a step-down voltage regulator that utilizes a power switching circuit to regulate the output voltage. It features two power MOSFETs connected in parallel, a diode, an inductor, and a capacitor. The MOSFETs control the flow of current between the input and output sources by switching on and off at a specific frequency determined by a frequency oscillator. The inductor is connected in series with the power source MOSFETs to help store energy and minimize the voltage change during each MOSFET switching cycle. The diode helps regulate the current and maintains the output voltage at a fixed level. Lastly, the capacitor is used to filter out any high frequency noise generated by the MOSFET switching.

All of these components work together to regulate the output voltage of the IH2415S DC-DC converter. When the input voltage varies, the MOSFETs switch on and off in order to maintain a constant output voltage. The inductor works to store energy during the off-cycle, and then releases it during the on-cycle to maintain the output voltage. The diode, on the other hand, regulates any excessive current and ensures that the output voltage does not exceed the input voltage. Finally, the capacitor helps reduce any high frequency noise generated by the MOSFET switching.

In summary, the IH2415S DC-DC converter is a highly efficient device that is used in a variety of industrial applications. It offers up to 94% efficiency under normal operation and 96% efficiency under light loads, and it supports coaxial DC input voltage from 12V to 48V. The module also offers overvoltage, overcurrent, undervoltage, and over-temperature protections and features a power switching circuit with two power MOSFETs, an inductor, a diode, and a capacitor. All of these components work together to regulate the output voltage of the IH2415S DC-DC converter and ensure its safe operation.
