DC to DC converters are useful for applications where direct current (DC) electrical energy needs to be sourced from a higher voltage than a constant voltage source or an alternating voltage source. One example is in the automotive industry, where energy from a car battery or alternator is converted into a lower voltage, usually around 12V or 24V, and then sent to on-board systems such as lights, audio, control panels, and other vital components. The MI-25Y-IY DC to DC converter is one such device that can help achieve this goal, and it has a wide array of potential uses in automotive, aerospace, and communications infrastructure.

MI-25Y-IY Features

The MI-25Y-IY converter is designed to converte higher-voltage DC inputs, typically up to 100V, down to lower-voltage DC outputs, typically 24V, 12V, or 5V. The converter operates with either positive or negative input/output voltages, making it highly versatile. Additionally, the converter is able to support very low-power output requirements, as low as 0.01A. It is also capable of operating in a wide range of temperatures, between -40°C and +105°C.

MI-25Y-IY Application Fields

The MI-25Y-IY DC to DC converter is best suited for use in automotive, aerospace, and communication infrastructure applications. In the automotive sector, the converter is useful for powering on-board components such as lights, audio systems, control panels, and electrical systems such as braking and acceleration that require a lower voltage than that supplied by the car battery or alternator. Additionally, the wide temperature range that the converter is able to operate in lends it useful for use in aerospace equipment and telecommunications infrastructure applications which are typically exposed to extreme temperatures either in a plane or outside of a building.

MI-25Y-IY Working Principles

The MI-25Y-IY DC to DC converter uses a buck-boost topology in order to convert higher voltage DC to lower voltage DC. Buck-boost topology is a type of switched-mode power supply wherein a MOSFET switches to either buck or boost the output voltage, as per the needs of the load. When the load requires a lower voltage, bucking is used to reduce the voltage. Conversely, when the load requires a higher voltage, the converter is switched to boost mode and the output voltage is increased. The constant switching between bucking and boosting of the MOSFET helps the input-output voltage conversion.

In addition, the MI-25Y-IY also uses an active PWM (Pulse Width Modulation) circuit to control the switching frequency of the converter. The frequency of the PWM signal is determined by an external resistor at the PWM pin, and it sets the switching frequency, which can range from 100 kHz to 500 kHz. Thus, the PWM signal helps to ensure that the output voltage is efficiently regulated.

Conclusion

The MI-25Y-IY DC to DC converter is an excellent choice for lower-power applications that require a wide voltage input and output range. It operates using a buck-boost topology and an active PWM circuit to efficiently regulate output voltage. Additionally, its ability to function in a wide range of temperature environments makes it a versatile choice for automotive, aerospace, and communication infrastructure uses.
