DC DC Converters are an important component of the electrical engineering world. This device allows for the conversion of energy between one circuit and another by utilizing different types of power sources to accomplish the desired result. In this discussion, we will focus on the REC7.5-2415SRW/H2/A/M/SMD/CTRL DC/DC converters and describe their application fields and working principles.

Application Fields

REC7.5-2415SRW/H2/A/M/SMD/CTRL DC/DC converter can be used in a variety of applications including but not limited to industrial automation, medical treatments, battery management, and power supply for automotive electronics. Some of the features offered for these type of converters are wide input voltage range from 4.5 Vdc to 20Vdc, high efficiency up to 91%, and allow for continuous dynamic loading or peak power. In addition to these features, the converters also offer are remote sense, enable/disable, output voltages potentiometer, Vin under-voltage lock-out, input over-voltage protection, input over-current shutdown, and thermal shutdown protections.

Working Principles

The working principle of the REC7.5-2415 SRW/H2/A/M/SMD/CTRL DC/DC converters involve the use of a step-down switching regulator to transform the input voltage into a steady and regulated output voltage. The switching regulator consists of four basic components: an inductor, a diode, a capacitor, and a switch. The switch is a transistor, which is turned off and on by the control circuit to control the flow of current in the circuit, while the inductor, diode, and capacitor act in unison to store and release electrical energy. When the switch is on, current flows through the inductor, storing energy in it. When the switch is off, the stored energy is released into the output voltage.

The input voltage is transformed into the desired steady output voltage by varying the “on” and “off” intervals of the switch. This is known as pulse width modulation (PWM). The duty cycle of the PWM is controlled by the control circuit, which is adjusted according to the current apply to the output terminal depending on the amount of load and the output voltage. The adjustment of the duty cycle ensures a steady output voltage, and thus, stable operation.

The REC7.5-2415SRW/H2/A/M/SMD/CTRL DC/DC converters can provide the required output regulating voltage with very high accuracy and features over-voltage, under-voltage, and over-current protection. As for the advantages of these types of converters, they are widely used in a variety of applications due to their low-cost and efficiency. In addition, they provide high levels of reliability, making them suitable for harsh industrial environments.
