DC-DC converters are used in a wide range of applications including the design of switching power supplies and DC lighting. The VE-B73-CW DC-DC converter has become one of the most popular devices used in these applications due to its great versatility and efficient operation. This article will discuss the application field and working principles of VE-B73-CW DC-DC converters.

VE-B73-CW DC-DC converters can be used in a variety of applications such as high-efficiency lighting systems, renewable energy systems, automotive systems, aviation systems, power supplies, and motor controllers. These devices are designed to operate with a wide input voltage range, from 15 V to 300 VDC, and a wide output voltage range, from 0.5 V to 18 VDC, while providing excellent regulation at low no-load losses. Furthermore, the input and output noise is minimised due to the low input impedance of the device and its wide temperature range, which is between -40°C and +85°C.

The working principle of VE-B73-CW DC-DC converters is based on the principle of high-frequency switching. This means that the device uses high-frequency switching to convert the input voltage to a higher voltage at the output. The high-frequency switching works by passing the input voltage through a series of MOSFETs, which are switched on and off at a high frequency. This switching creates a pulse-width modulation (PWM) signal, which is then converted into a DC voltage at the output. The efficiency of the device is improved by the use of an integrated synchronous rectifier circuitry, which eliminates switching losses.

The VE-B73-CW DC-DC converters are also equipped with protection features such as a thermal shutdown circuit and an under-voltage lockout circuit. The thermal shutdown circuit ensures that the device will not overheat and shut down in case of an unusual overload condition, while the under-voltage lockout circuit ensures that the device will not start up if the input voltage is too low.

VE-B73-CW DC-DC converters also feature a voltage loop feedback which helps to maintain the output voltage at a specific level. This is achieved by monitoring the output voltage and feeding this information back to the control circuit, which makes adjustments to the voltage to maintain the desired voltage level. In addition, the device can be configured to turn off or shut down if the output voltage exceeds a certain value.

In conclusion, the VE-B73-CW DC-DC converters offer great versatility and efficient operation in a wide range of applications. These devices can operate with a wide input voltage range and provide excellent regulation and low no-load losses. Furthermore, they are equipped with protection features such as a thermal shutdown circuit and an under-voltage lockout circuit, and include a voltage loop feedback which helps to maintain the output voltage at a specific level.
