Introduction:DC-DC converters, also known as DC-to-DC converters, are electrical devices used to convert one voltage to a different voltage or voltage waveform of the same frequency. The QSB35024S28 is a specifically designed DC-DC converter with an output of 24VDC and an input voltage range of 18-36VDC.Features: The QSB35024S28 is specially designed for use in applications that required a stable and reliable power supply. Its wide input voltage range, high switching frequency, low output ripple and low radiated interference make it ideal for a range of applications. EfficiencyThe QSB35024S28 has an efficiency rating of up to 94%, so it requires less power while delivering a higher output. It also features advanced burst mode operation, allowing it to optimize its performance from light load to full load. Protection Features: The QSB35024S28 has several integrated protection features that safeguard the device and the system against overload and short circuit. These features include thermal overload protection, short circuit protection, overvoltage protection, and overcurrent protection.Applications: The QSB35024S28 is suitable for a wide range of applications, such as automotive, industrial, medical, and communications systems. It is commonly used in industrial automation, electric vehicles, chargers, controllers, and solar power systems.Working Principle:The QSB35024S28 works on the principle of buck-type, non-isolated DC-DC switching converters, which convert a single-voltage input into a higher-value stable DC output. The device contains two main components: an inductor and a switch. The inductor stores energy and the switch controls the flow of energy. When the switch is closed, energy is stored in the inductor and the output voltage is increased. When the switch is open, the stored energy is released and the output voltage is decreased. The operation of the device is controlled through the use of feedback signals, which adjust the duty cycle of the switching cycle to maintain the output voltage constant.Conclusion:The QSB35024S28 is a high performance DC-DC converter designed to provide reliable and stable power for a variety of applications. Its wide input voltage range, high efficiency, and robust protection features make it an ideal choice for use in industrial, automotive, medical, and communications systems. It works on the principle of buck-type, non-isolated DC-DC switching converters and it provides a stable output voltage despite changes in the input voltage.
