DC DC Converters

DC DC converters are an essential component of many electrical systems, providing a way to change the voltage of an electrical source. The SUS101205B is a reliable and cost-effective solution for DC DC voltage conversion, and the following is an overview of its Application Field and Working Principle.

Application Field

The SUS101205B is designed to convert a wide range of input voltages into a regulated output voltage, and its application field includes utility systems, home appliances, automotive, telecom, computer, industrial and medical equipment. It is particularly suited for applications that require high efficiency, fast response time, low electromagnetic interference and low cost. It is capable of providing up to 5A continuous current and is also well suited for high current applications, such as motor drives and PC power supplies.

Working Principle

The SUS101205B is a step-down converter, meaning that it takes an input voltage of up to 50V and converts it to a regulated output voltage that is usually between 5V and 18V. The output voltage level is adjustable with a simple trimmer, allowing for precise adjustments.Inside the converter is a buck converter circuit. This circuit consists of a power transistor, an inductor, a diode, a capacitor, and various resistors and capacitors. The transistor switches current through the inductor to the output, and the diode and capacitor ensure that the current does not flow backwards. The inductor stores energy and releases it to the output, resulting in a smoother output voltage waveform.The SUS101205B also features a built-in temperature protection function. This helps protect the components from damages caused by excessive temperatures, which is particularly beneficial for applications like motor drives that require high amounts of current.In summary, the SUS101205B is an efficient and cost-effective DC DC converter suitable for a wide range of applications. It is capable of converting a wide range of input voltages into a regulated output voltage, and features an adjustable output level, temperature protection, and fast response time.
