It is a closed-loop control converter capable of delivering up to 3A of output current with high efficiency, programmable switching frequency and a fast transient response.

Application Field

TLV62130ARGTR is designed for use in many different applications. Some of its most common applications include automotive power management, LED lighting, HVAC systems, industrial instrumentation, removable device batteries, video game consoles and other consumer electronics. Its wide input voltage range, high efficiency and low output noise makes it highly suitable for these applications.

Working Principle

TLV62130ARGTR is a synchronous buck converter which operates similar to a conventional buck converter but with an added current sensing circuit connected between the output and the power path that senses the current between the input and output. The current feedback signal is then compared to the reference voltage generated by an internal error amplifier to determine the switching losses. This current-mode control loop compensates for duty-cycle variations caused by input/output voltage variations and/or load changes, thereby making the voltages stable and maintaining a fixed output voltage. The output voltage is determined by the ratio between the resistors connected to the programming pin and the feedback pin. It also offers protection from over-current and over-temperature conditions. Furthermore, TLV62130ARGTR can be programmed to a wide range of frequencies for energy-efficiency and dynamic response.

Conclusion

TLV62130ARGTR is a highly reliable and efficient dc-dc synchronous buck converter from Texas Instruments. It offers a wide input voltage range, high efficiency and low output noise, making it suitable for a wide range of applications such as automotive power management, LED lighting, HVAC systems, industrial instrumentation, removable device batteries and many other consumer electronics. It operates based on a current-mode control loop which compensates for variations in the input/output voltage, allowing for a stable output voltage. In addition, it provides protection from over-current and over-temperature conditions and can be configured with a variety of frequencies for enhanced performance.
