V72B36M250BN

DC DC converters are power electronic circuits which convert a higher DC voltage to a lower voltage, either isolating the two, or non-isolating depending on the circuit topology. They are divided into two categories, depending on the mode of operation: linear converters and switch mode or switching converters. The V72B36M250BN is a switch mode DC DC converter, and is typically used in those applications requiring a higher voltage input than the output.

The V72B36M250BN is a high-efficiency DC-DC converter for applications that require high power density. It has an operating frequency of 500 KHz and can deliver a peak output current of 250 Amps. It has a wide input voltage range of 9 – 36 VDC, and an adjustable output voltage of 0.6 – 36 VDC. It is also protected from overvoltage, overcurrent and overtemperature conditions.

The V72B36M250BN is one of the more popular DC-DC converters, typically used in systems which require medium and high power levels but are confined to small areas due to space restrictions. Typical applications for the V72B36M250BN include communication systems, industrial automation, medical devices, and electric vehicle charging.

The V72B36M250BN is a switching regulator which incorporates a current mode control topology. This enables it to achieve high-efficiency conversion, while also providing many advantages over linear regulators. One of the main benefits of using a switch mode converter is its ability to provide a high output current while maintaining a low output voltage ripple.

The circuit consists of an input filter, a high frequency switch, an output filter, an output voltage sensing circuit, and a control unit. The control unit is responsible for generating the appropriate switching waveforms, and controlling the duty cycle of the switch to regulate an output voltage set point. It also regulates and monitors the input and output voltages and current for protection from any overcurrent or overvoltage conditions.

The input filter is used to reduce any line noise that may be present on the input voltage source. The components of the filter will depend on the input frequency and the desired attenuation. The high frequency switch is the main component of the converter and controls the transfer of power from the input source to the output load. It is usually a MOSFET or IGBT. The output filter is used to reduce the voltage ripple that is present between the input and output, ensuring that the output voltage is as close to the set-point as possible. The output sensing circuit is used to monitor the output voltage and sends feedback to the control unit, in order to regulate the output voltage.

In conclusion, the V72B36M250BN is a high-efficiency switch mode DC-DC converter typically used in space-restricted applications that require high power levels. It has a wide input voltage range and can deliver a peak output current of 250 Amps. Its high-frequency switch, along with its current mode control topology, make it ideal for applications that require minimal output voltage ripple. The input and output filters, as well as the output voltage sensing circuits, ensure that the output voltage is as close to the set-point as possible.
