DC-DC converters are an integral part of many electronic systems, providing the ability to increase or decrease the voltage within a circuit. The convergence of multi-functional electronics has created a number of different industry standards. The VE-JN2-CX-B1 is one such example, a device specifically designed for the conversion of isolated alternating current (AC) to direct current (DC).

The VE-JN2-CX-B1 is a low-cost, relatively small, power-conversion unit, possessing a range of features and capabilities. The device is especially suitable for a number of applications, from use in industrial power supplies and automation systems, to controlling the input of voltage on embedded microcontroller systems.

The VE-JN2-CX-B1 consists of three main components: an AC input rectifier, a DC–DC converter, and an output unit. The input rectifier is made up of surge protection diodes and an electrolytic capacitor, along with an opto-isolator. This converts the incoming AC signal to a flat DC voltage and provides isolation from the control electronics that will later regulate the output.

The DC-DC section of the VE-JN2-CX-B1 consists of an isolated flyback transformer and a power switch. The purpose of this is to convert the incoming DC voltage into an output of variable DC voltage. To do this, a voltage feed-back mechanism is used to monitor the output voltage and adjust the power switch accordingly, maintaining the required output voltage.

The final element of the VE-JN2-CX-B1 is the output section. This consists of a filter capacitor and is used to ensure that the output voltage is as clean and ripple-free as possible. By combining all these elements, the device can accurately control and regulate the output voltage to within a few millivolts of the reference voltage.

In order to protect the VE-JN2-CX-B1 from overloads, it is equipped with a thermal shutdown feature. This works by monitoring the temperature of the device and, when it exceeds a certain level, it will shut down the output voltage, ensuring that no damage is done to the internal components.

The VE-JN2-CX-B1 is an incredibly versatile and reliable power converter, suitable for a wide variety of applications. The device provides a full range of features such as fast transient response, extreme low self-consumption, and full protection features, making it an ideal choice for any embedded system or industrial power supply.
