Introduction:
The V72B15T250BN is a DC-DC converter designed to convert direct current (DC) sources into lower voltage DC outputs. It is part of a range of DC-DC converters used to transform different levels of voltage within the range of 1.8 V to 15 V. This article will focus on the application field and working principle of the V72B15T250BN.

Application Field of V72B15T250BN:
The V72B15T250BN is used to meet a number of different power requirements. It is suitable for applications which require very tight regulation, such as battery-charging, or other high accuracy power systems. It is also used in many low to mid power applications such as domestic appliances and LED lighting. Its wide operating range and input voltage range gives it a wide range of applications, from 72 W down to 0.125W.

Working Principle of V72B15T250BN:
The V72B15T250BN is designed to be a constant voltage source. The output voltage is controlled by a feedback loop which uses an error amplifier, a current sense amplifier and a power MOSFET transistor to control the output voltage. The input voltage is rectified and then fed into a step-down transformer in order to reduce the voltage. The shuttle voltage is then rectified by an internal rectifier and stored in a capacitor. It is then smoothed out by an LC filter.

The voltage output is then regulated by the error amplifier. When the output voltage begins to increase, the error amplifier begins to decrease its output. This causes the gate of the power MOSFET transistor to be driven to a lower voltage and allows less current to flow through the circuit. Thus the output voltage is lowered back to its desired level. The same process is applied for decreasing output voltage.

Conclusion:
The V72B15T250BN DC-DC converter is a versatile device which has a wide range of applications for its use. It can be used to transform all sorts of inputs into lower voltage outputs with very tight regulation. Its working principle utilises a feedback loop with various components such as error amplifiers and a power MOSFET transistor to provide a constant output voltage.
