DC-DC Converters refer to power converters which are used to convert a DC input voltage to another desired DC voltage level. In recent years, the development of DC-DC Converters has been rapid, with more and more options available on the market. One such DC-DC Converter is V300C48M75B3. In this article, we will learn about the application field of V300C48M75B3, as well as its working principle.

The primary application field of V300C48M75B3 is power conversion in automotive applications. This DC-DC Converter is a non-isolated 3-watt dc/dc converter with an input voltage range of 2.375 – 5.5 Vdc, and an output voltage range of 0.6 – 36 Vdc. It is designed to meet automotive quality requirements and has been developed specifically for the rigorous automotive environment. It is suitable for applications such as current-sensor circuitry for engine management, power supplies for instrumentation, harmonic-attenuation for audio circuits, and backup supply circuits.

The working principle of V300C48M75B3 is relatively simple. When it is supplied with an input voltage, the voltage is first reduced to an intermediate voltage level before being converted to the desired output voltage level. This is done via an inductor which is used to store energy and then release it at a regulated voltage level. The output voltage is then stabilized with the help of a low ESR output capacitor. The output voltage is also protected against overload, high-temperature overload, and overcurrent conditions. It features a thermal shutdown, a soft-start, and a thermal-shutdown protection.

The technical specifications of V300C48M75B3 are as follows: its input voltage is 2.375 – 5.5 Vdc and its output voltage is 0.6 – 36 Vdc. Its ripple and noise is less than 200 mVpp and its output current is adjustable via an external resistor. Additionally, it has a start-up current of less than 2 mA and a power efficiency of up to 90%.

In summary, V300C48M75B3 is a 3-watt DC-DC Converter with a range of technical specifications, making it suitable for use in automotive applications. Its working principle involves the use of an inductor to reduce the input voltage to an intermediate voltage before it is converted to the desired output voltage. Additionally, it is protected against overloads, high-temperature overloads, and overcurrent conditions, meaning that it is effective for use in many automotive uses.
