TL2575HV-15IN

The TL2575HV-15IN DC-DC switching regulator is a popular choice for applications requiring adjustable high-efficiency low-noise power conversion. Specializing in wide input and output ranges, it can be programmed for output voltages up to 15V. Additionally, the high switching frequency helps minimize filter components.

This particular feature is what makes the TL2575HV-15IN so useful for multiple application fields. These include, but are not limited to, Audio/Video, Communication Systems, Consumer Electronics, Industrial Automation, Point-of-Load (POL), Power Loss Metering, and Telecommunications.

The key to the TL2575HV-15IN regulator’s versatility lies with its advanced circuit topologies. Different algorithms are employed depending on the design and the end application, such as maximum efficiency conversion, low noise operation, and bulk voltage/current regulation.

Working principle of the TL2575HV-15IN DC-DC switching regulator is relatively simple and efficient. First, the input voltage is rectified by a full-bridge rectifying circuit into a series of pulses, with the output voltage being determined by the applied frequency and the ratio of the current transformer. The rectified voltage is then filtered, stabilized, and the output voltage is eventually delivered.

Next, the high-frequency switching regulator power control is carried out by the integrated control IC. It is controlled by the externally applied voltage, which can be compared to the feedback voltage from the output and adjusted as necessary. This in turn controls the duty cycle of the power switch, thus establishing and maintaining the output voltage. The higher the frequency, the faster the changes in duty cycle and therefore the regulation of the output voltage and current.

The TL2575HV-15IN DC-DC switching regulator includes several features beyond those mentioned above, such as built-in protection, soft start, thermal shutdown, and overvoltage/undervoltage protection. Additionally, its small size and robust design allows it to be integrated into tight spaces and harsh environments, making it extremely reliable and cost-effective.

In conclusion, the TL2575HV-15IN DC-DC switching regulator is an excellent choice for applications requiring adjustable, efficient, and low-noise power conversion. With an extensive range of input and output ranges, it is ideal for a variety of application fields including Audio/Video, Consumer Electronics, Industrial Automation, and Telecommunications. Its advanced circuit topology and various protection features make it a reliable and cost-effective solution.
