DC-DC converters are an important part of designing and implementing a reliable, efficient, and cost-effective power system. The capabilities these converters offer, from efficiently converting input voltage levels to isolating different voltage systems, makes them an integral part of the power system. This article will discuss the V375B3V3M100BS application field and working principle.DC-DC converters take a direct current input source and convert it into a different direct current voltage output. The output voltage is usually adjustable as it is beneficial in applications such as powering boards or modules with variable power needs and gain/ratio adjustment. V375B3V3M100BS is an isolated type DC-DC converter which combines the features of high safety, high efficiency, high reliability, and wide input voltage range. It is specially designed for low output voltage such as 3.3V applications in a board-mounted switching power supply.V375B3V3M100BS offers a wide input voltage range between 4.5V and 17V with a maximum output current of 100mA. It is designed with a high isolation voltage, up to 1500V, and has an extended operating temperature range from -40°C to 85°C. The V375B3V3M100BS is ideal for low voltage applications such as supplying power to LED lights, RF amplifiers, analog-to-digital converter (ADCs) and digital-to-analog converter (DACs) as well as low voltage logic circuits. The working principle of the V375B3V3M100BS is based on a flyback circuit. A flyback converter is an isolated DC-DC converter which uses a transformer for its magnetically coupled input and output. The name “flyback” comes from the behavior of the output voltage when the primary winding current is interrupted. As the current falls off, the dying magnetic field causes a high voltage spike across the secondary winding, before the output voltage drops to zero. This high voltage spike is referred to as the flyback voltage.The converter consists of four functional components, the primary switch, the transformer, the rectifier, and the output filter. The primary switch is driven by the control circuit and it is charged with energy when it is ON and discharged when it is OFF. During the ON time, the energy stored in the transformer is fed to the output, while during the OFF time, the energy stored is recovered as a flyback voltage. The rectifier is used to rectify the load current drawn from the output and the EMI filter is used to filter out the high frequency switching noises.The V375B3V3M100BS converter can achieve higher efficiency, lower no-load losses, and fast transient response. It is also resistant to shock and vibration.The V375B3V3M100BS can obviously benefit a variety of projects due to its impressive specs. It can successfully handle applications ranging from basic power supplies to more complex switched-mode circuits. The high input voltage range and isolated design makes this converter ideal for a variety of applications. Moreover, the wide operating temperature range provides a great advantage in applications that require reliable power over a range of conditions.Overall, the V375B3V3M100BS is a great choice for low voltage applications due to its wide input voltage range, high efficiency, and high voltage isolation. The flyback topology also makes it a suitable powering solution for applications that require high transient response and low EMI, making it ideal for powering many of today’s electronic circuits.
