DC-DC converters (buck-boost converters) are electronic components that convert direct current (DC) from one voltage level to another. The TDR 3-0522 is a compact and efficient DC-DC buck-boost converter designed for high-current applications. It is ideal for battery chargers, high-power LEDs, and applications requiring adjustable output voltage. This article will explain the TDR 3-0522 DC-DC buck-boost converter’s application field and working principle.The TDR 3-0522 is a high-efficiency DC-DC buck-boost converter. It can continuously convert a 4.75V to 28V DC voltage to an adjustable output voltage ranging from 4.75V to 28V. It features a wide voltage range, making it suitable for a variety of applications including battery chargers, high-power LEDs, and other applications that require adjustable output voltage. In addition, the TDR 3-0522 features a high and low-current protection function, ensuring output stability against extreme load changes and over-current conditions. It also offers adjustable operating frequency, making it ideal for applications that require power conversion efficiency and good EMI performance.When the input voltage of the TDR 3-0522 DC-DC buck-boost converter is within specified limits, the power-on reset circuit (PoR) will turn on the controller IC. The controller IC then stores the input voltage in its internal register, and uses a series of voltage dividers and reference voltage sources to compare the internal voltage reference to the stored input voltage. When the comparison indicates that the input voltage is within the specified range, the controller IC will send a signal to the power FETs to begin the switching process. The TDR 3-0522 uses an advanced FET switching topology to convert the input voltage to an adjustable output voltage. The output voltage is then regulated by the controller IC, which constantly adjusts the duty cycle of the FETs to maintain the desired output voltage.The TDR 3-0522 DC-DC buck-boost converter is an efficient power solution for a variety of applications requiring adjustable output voltage. It is ideal for battery chargers, high-power LEDs, and applications that require adjustable output voltage. Its wide voltage range and adjustable operating frequency make it a reliable and versatile power converter. In addition, its advanced FET switching topology ensures high-efficiency operation and good EMI performance. Lastly, its integrated protection functions provide safeguards against extreme load changes and over-current conditions, ensuring output stability.The specific data is subject to PDF, and the above content is for reference
