Application Field and Working Principle

The combination of a robust high efficiency converter, high bandwidth, and small size makes the TL2575HV-12IKTTR suitable for many different applications such as automotive, industrial, medical, and consumer applications. In automotive, it is perfect for automotive infotainment systems, ECU, among other devices. TL2575HV-12IKTTR can also be used in industrial applications requiring stringent electrical and thermal performance and robustness such as wide ambient temperature operation, high efficiency, and low EMI. Its performance makes it suitable for industrial, medical, and consumer applications including lighting systems, standby power, telecom, gaming, and home appliances.

The TL2575HV-12IKTTR’s switching voltage regulator works by taking an input voltage and using it to power its two MOSFETs. When the MOSFETs are off, the voltage across the inductor is zero. When the MOSFETs are on, however, the voltage across the inductor is equal to the input voltage minus the sum of the on impedance and the off impedance of the MOSFETs. This voltage is stored in the inductor and then used to provide the output voltage. The output voltage is regulated using a control loop that adjusts the duty cycle of the MOSFETs depending on the output voltage. When the output voltage is too high, the duty cycle is decreased and vice versa.

TL2575HV-12IKTTR is also equipped with added protection features such as current limit, over-voltage protection, over-temperature protection, under-voltage lockout and output short circuit protection. These features make the TL2575HV-12IKTTR an ideal device for a wide range of applications.

In summary,the TL2575HV-12IKTTR is a high efficiency DC-DC synchronous step-down switching voltage regulator ideal for use in automotive infotainment systems, ECU and industrial, medical, and consumer applications requiring stringent electrical and thermal performance and robustness.
