The V28A8H200BG3 (The “V28A8H200BG3”) is a DC-to-DC converter used in a variety of applications. This device provides a high efficiency power transfer between two different input voltage levels, such as between a low voltage source and a high voltage load. It is a non-isolated regulated Buck converter, which is a type of modified Buck converter, that operates with two sources and two loads.The V28A8H200BG3 is particularly well-suited for use in a wide variety of commercial, industrial, and medical devices such as transformers, integrated circuits, and medical diagnostics and imaging equipment. Its high efficiency rate, low noise level, fast transient response, and large output voltage range make it particularly useful for power management applications. It also features integrated protection features, such as over-voltage protection and over-current protection, and is capable of withstanding high inrush current and rollover load conditions.The V28A8H200BG3 offers a wide input voltage range from 6 V to 85 V and consistent output current from 0.30 A to 2 A, with a peak output current of 2.2 A. Its output voltage remains very stable across a wide input voltage and output current range.The V28A8H200BG3 is designed for voltage step-down (also known as buck) applications, where the output voltage is smaller than the input voltage. The output voltage is regulated between 6 V to 49.95 V Adjustable by an external resistor. The step-down ratio is determined by the ratio of the external resistor to the total resistance of the two resistors inside the device.The operation of the V28A8H200BG3 can be summarized in five simple steps. First, the input voltage is applied to the input pins of the V28A8H200BG3. Second, the V28A8H200BG3 uses its internal switch to reduce the input voltage to the desired output voltage, such as 6 V to 49.95 V depending on the external resistor value and the total resistance of the two resistors inside the device. Third, the output voltage is passed through the inductor inside the device, where it is filtered and regulated. Fourth, the output voltage is passed through the capacitor which helps minimize noise and ripple. Lastly, the output voltage is passed to the output pins of the V28A8H200BG3.The V28A8H200BG3 offers many advantages. It is capable of providing high efficiency and low EMI, with an efficiency rating up to 97%. It also presents excellent transient response and fast load transients. The device is also capable of withstanding high input surges, overvoltage, overload, and short-circuit conditions.The V28A8H200BG3 is an ideal choice for a wide variety of power management and industrial applications. It is easy to use and offers excellent performance with a long service life. It is also small in size and lightweight, making it an ideal choice for applications where space is limited.
