The SUS100515BP DC to DC converter is one of the types of DC DC converters, specifically a buck converter. It is used to deliver a steady, precise output voltage from an unregulated input voltage, that may vary from anywhere between eight to sixteen volts.

Application Field

This type of DC to DC converter is mainly used in automotive, military, and industrial applications, it is especially designed for use in braking systems for electric vehicles. It is also used in the aerospace and aviation industry, primarily for flight control systems, as well as in professional audio and communication systems, where precision is essential for proper operation.

Working Principle

The SUS100515BP operates in a buck mode, which means that it can reduce the input voltage from a higher value to a lower value, while maintaining a steady output voltage. It takes in a voltage of 8-16V, and outputs a steady 5V voltage. It does this by the use of two transistors arranged in a configuration known as a \'voltage divider\'. This configuration allows for a steady voltage output, with the output being regulated by the transistors.

The transistors act as a switch, and are used to regulate the current flowing in the circuit. When the input voltage is greater than the output voltage, the transistors act as an open circuit, allowing the current to flow into the output. This increases the output voltage, and the transistors switch back to a closed circuit, limiting the current and maintaining the output voltage. When the input voltage is less than the output voltage, the transistors act as a closed circuit, preventing the current from flowing into the output. As the input voltage drops, the transistors open again and the output voltage falls, and the transistors switch back to the closed circuit when the output voltage reaches the desired level.

The SUS100515BP is highly efficient due to its use of high frequency switching, giving a typical efficiency of 96.5%. It is also capable of operating in a wide range of temperatures, from -40°C to 85°C, making it suitable for a variety of applications. It is also lightweight and small in size, making it easy to install in tight spaces.

The SUS100515BP is a highly reliable solution when it comes to delivering a steady, precise output voltage, and is a popular choice in automotive, military, and industrial applications. Its high efficiency, wide range of operating temperatures, and small form factor make it well suited for use in a variety of situations.
