DC-DC converters are a type of electrical power converter which take an input direct current (DC) voltage and output a different, regulated output DC voltage. The V72B8E150BL2 is a dual input DC-DC converter designed to accept input from a variety of sources, including USB, a computer or battery power, and output a stable DC voltage at up to 6A, with a maximum voltage of 15V.

Input & Output

The V72B8E150BL2 DC-DC converter can accept either positive or negative input voltage (4.5V to 36V). This allows the converter to be used in a broad range of applications, from using a computer power supply to USB, battery power or isolated systems. The output voltage of the converter is adjustable from 8V to 15V, with a maximum output current of 6A.

Features

The V72B8E150BL2 DC-DC converter has a host of features designed to make use as simple as possible. It has a high thermal performance, with a thermal stability of up to 70 °C, allowing it to operate even in higher temperature environments. It also has a low output ripple, allowing the converter to retain a more stable voltage across its range. To protect the converter from over-voltage, over-current and short circuit conditions, the converter is equipped with a built-in voltage and current limit circuit. The converter also has an automatic input voltage detection feature which allows it to adapt to different input levels, as well as a power good indicator to alert the user if an issue has occurred.

Applications

The typically applications for the V72B8E150BL2 DC-DC converter includes powering of digital and embedded systems, providing a regulated voltage to video surveillance systems, powering LED lighting, powering industrial or scientific instrumentation, and powering motor control systems.

Working Principle

In order to provide a steady DC output, the V72B8E150BL2 DC-DC converter works by taking the received input voltage and transforming it to an intermediate voltage and then switching the output. The converter uses an on-board switching controller, which works by switching the incoming DC source voltage at a very high frequency, allowing it to supply a stable output voltage. This is done by controlling the switch state using an on-board integrated circuit that is configured to cycle the voltages at a very high frequency, allowing the output voltage to be kept at a consistent level, even under fluctuating input conditions.

Safety

It is important to ensure that the converter is set-up correctly and that the device is used in a safe manner in order to avoid any potential hazards. As such, the V72B8E150BL2 DC-DC converter is equipped with an over-current and over-temperature protection feature. This means that if the device detects an over-current situation, it will automatically shut off the output, thus preventing any potential damage to the device or the connected circuitry. This also prevents damage from occurring to the device if the temperature exceeds the set-point.

Conclusion

The V72B8E150BL2 DC-DC converter is a reliable, versatile, and powerful device, and a great choice for the powering of various digital systems, industrial or scientific instrumentation and LED lighting. It is designed with a host of features such as a voltage and current limit circuit, and high thermal performance, to allow it to operate even in higher temperature environments. Combined with the ability to provide regulated output voltage over a wide range of input sources, it makes an excellent choice for a broad range of applications.
