TPS62092RGTT Integrated Circuits (ICs)

The TPS62092RGTT is a compact, high-efficiency, and cost-effective synchronous step-down DC-DC converter designed for a wide range of applications. With a typical input voltage of 5V, it supports an output voltage from 0.5V to 8V and provides 5A of output current. It is a great choice for mobile, gaming, computing and industrial applications.

Application Field

The TPS62092RGTT is one of a family of advanced, monolithic, synchronous, step-down DC-DC switching regulators, providing the capability to deliver up to 5A of continuous output current with an input voltage range of 2.3V to 5.5V and an output voltage range of 0.5V to 8V. This device offers very low quiescent current, tight line and load regulation, as well as thermal protection. The device has very low output ripple and also includes integrated internal soft start and overcurrent protection. The TPS62092RGTT can be used in a wide range of applications including computing, networking, mobile and handheld devices, gaming, computing and industrial.

Working Principle

The TPS62092RGTT is a current mode DC-DC switching regulator, which means that the voltage is sensed at the load instead of the input side. The load current is sensed by the sense resistor, which is connected in series with the load. A copy of this signal is sent to the signal conditioning block, which provides a filtered and amplified signal for the current sensing block. The current sensing block then uses this signal to control the voltage across an internal switch, which is connected in series with the inductor and the load. This allows the regulator to deliver the required output voltage while limiting the output current. The TPS62092RGTT also has an internal low drop-out regulator that is used to provide power to the device when the input voltage is lower than the nominal value.

The TPS62092RGTT is also equipped with a few diagnostic and protection features. First, it has an overcurrent limit feature which will shut off the device if the output current exceeds a predetermined limit. Second, the device has an overtemperature protection, which will prevent overheating of the device. Lastly, the device has a soft-start feature, which will slowly ramp up the output voltage to its desired level and reduce the inrush current. This helps to improve efficiency and reliability.

To summarize, the TPS62092RGTT is a current mode switching DC-DC regulator that provides up to 5A of output current and has an input voltage range of 2.3V to 5.5V and an output voltage from 0.5V to 8V. It is a great choice for mobile, gaming, computing and industrial applications due to its low quiescent current, tight line and load regulation, as well as thermal protection. It also has an overcurrent protection, overtemperature protection and a soft-start feature.
