DC DC converters are essential components in power supply systems. Through these components, energy from one DC source is transferred to another DC voltage source, making them highly versatile and widely used in electrical applications. The purpose of this paper is to discuss the application field and working principle of a specific type of DC DC converter, the VE-B43-EV-F4.

Application Field of VE-B43-EV-F4

The VE-B43-EV-F4 is a high-performance DC DC converter designed for use in a variety of industrial, commercial, and military applications. It can provide up to 15 W of power output at the output voltage range of 5.0 V to 15.8 V. The input voltage range is 3.3 V to 10 V allowing for an extended range of applications.

The VE-B43-EV-F4 is specifically designed for applications where space is at a premium such as on mobile electronic equipment, instrumentation, and telecom systems. It features a very small footprint of 23mm × 17mm, allowing it to be placed in areas where other converters are not able to fit. Additionally, its low EMI characteristics mean it can be used without generating significant levels of electromagnetic interference.

Working Principles of VE-B43-EV-F4

As a DC to DC converter, the VE-B43-EV-F4 works by converting a DC input voltage to a different DC output voltage. This is done using the bridge-mode circuit topology. This type of circuit topology has many advantages, such as low electromagnetic interference, low output ripple, as well as high power efficiency. It works as follows:

The input voltage is first rectified and then filtered using an input filter to reduce the input ripple. The input voltage is then sent to the control IC, which regulates the output voltage using a pulse-width modulation technique. The PWM signal is then used to drive a series of power transistors, which switch the input voltage between the output capacitor and ground. This process is repeated at a high frequency (up to 800 kHz) which switch the input voltage to the output capacitor resulting in an output voltage, thus converting the DC input voltage to a different DC output voltage. The output voltage is then filtered and regulated to the desired level.

Conclusion

The VE-B43-EV-F4 is a popular DC DC converter used in many applications where space is limited and power efficiency is critical. Its bridge-mode circuit topology makes it especially suitable for applications where low EMI is required and its small footprint makes it an ideal choice for deployments where space is at a premium. The working principle of the VE-B43-EV-F4 is based on rectifying and filtering the input voltage before sending it to the control IC, where it is then regulated using pulse-width modulation, and switched between the output capacitor and ground to produce the desired output voltage.
