DC DC Converters

DC–DC converters are electronic circuits which convert direct current (DC) from one value to another. They are considered as a separate field in power electronics since the power range is usually below one kilowatt. These devices may include buck converters, boost converters, buck-boost converters, SEPIC converters, Cuk converters and flyback converters.

V150B8H200BN

The V150B8H200BN is a high-performance, high-reliability DC–DC converter designed for applications such as telecommunications and computer systems where a wide input voltage range and high power density are essential. This device provides regulated outputs with individual regulation for each channel. The maximum input voltage range is from 7V-160V, and the maximum output voltage is 28V. The maximum output power is 200W.

Application Field and Working Principle

The V150B8H200BN is suitable for a wide range of applications that require precise regulation of the output voltage, including power supplies for computers, telecommunication equipment, industrial control systems, and automotive applications. It is also ideal for many battery management systems.

The V150B8H200BN converter can operate in either Continuous Conduction Mode (CCM) or Discontinuous Conduction Mode (DCM), depending on the load conditions. In CCM , the applied voltage and the input current are in phase with each other, while in DCM, there is an offset between the voltage and the current. In both modes, the output voltage is regulated by the duty cycle of the switching device, which is sensed by an internal feedback circuit.

To protect the converter from overloads, it has a current limit protection. This will shut down the converter when the output current exceeds a certain limit. It also has a thermal protection, to prevent the converter from overheating by shutting down the converter when the internal temperature reaches a certain level. The converter also has short circuit protection to prevent a short circuit on the output.

For improved performance, the V150B8H200BN features a synchronous rectification scheme which minimizes power consumption and heat dissipation. The converter includes an integral EMI filter, which reduces conducted and radiated emissions to meet various international standards without the need for external components.

Conclusion

The V150B8H200BN is a high-performance, high-reliability DC–DC converter designed for a wide range of applications. It offers a wide input voltage range and high power density, individual regulation for each output channel, and extensive protection features. The converter also features a synchronous rectification scheme which improves efficiency and an integral EMI filter which reduces emissions. Overall, the V150B8H200BN is a reliable and effective solution for applications that require precise voltage regulation.
