It has a maximum operating temperature range of -40°C to +85°C, making it suitable for many environments. The main regulators feature an integrated soft-start, overvoltage and undervoltage protections, as well as thermal shutdown and current limit protection. The device is available in a 16-pin THM package suitable for SMT mounting.

Working Principle

The TL2575HV-33IKTTR works on the principle of a buck/boost converter, which is able to regulate the input voltage to the output voltage by altering the duty cycle of an oscillator. The TL2575HV-33IKTTR is capable of supplying a maximum of 15 A output current, with a voltage conversion range of 4.5 V to 25 V, with an efficiency of up to 93%.

The TL2575HV-33IKTTR utilizes synchronous rectification technology to provide maximum efficiency, with zero current rush. This mechanism allows the controller to switch current through the MOSFETs at a critical time, resulting in losses from the increasing current being eliminated. This provides improved efficiency and cooling of the regulator, allowing it to operate in higher power operation.

Protection Features

The TL2575HV-33IKTTR also offers a comprehensive suite of protection features for increased reliability. It includes an integrated soft-start, which helps to reduce the input inrush current and minimize voltage spikes when the regulator turns on. It also has undervoltage lockout, overvoltage protection, current limit protection, and thermal shutdown.

The TL2575HV-33IKTTR also features a low-standby mode, which allows the converter to be used in battery-powered systems with minimal power consumption during idle time. This feature is particularly suited for automotive, industrial, and communication applications where power conservation is important.
