Texas Instruments launched TI first DC / DC buck-boost converters, which combine programmable input current limits and integrated dynamic voltage adjustment functions, can extend battery life at least 50%. The TPS63900 keeps the industry's lower static current (IQ) 75 NA, providing 92% efficiency at 10 μA, and the output current is three times the competitive product, which can help engineers extend battery-powered industrial and personal electronic products. life.

The universal challenge facing engineers is to provide sufficient output current while designing low IQ, with intelligent grid applications for remote and wireless M-BUs, such as narrowband Internet access (IoT), Bluetooth low power consumption. Send a signal between the network. The TPS63900 can help engineers save energy in battery-powered wireless connection applications.

Integrated dynamic voltage adjustment function, extend battery life at least 50%

The TPS63900 integrates dynamic voltage adjustment capabilities, which maintains the system to maintain the lower voltage required for efficient operation while providing power to the battery life and reduce the maintenance required for industrial applications.

This feature enables design engineers to optimize the power architecture of ultra-low power sensors and wireless connection integrated circuits, thereby supporting applications that use primary batteries to run for at least 10 years. For example, a buck-boost converter can be used with Ti's MSP430FR2155 safety sensor or wireless IOT sensor to monitor the vibration of the water pump, perform predictive maintenance and help reduce costs.

Programmable input current limits better improves the capacity and security of available battery

As the minimum integrated programmable input current limit, TPS63900 can efficiently charge the supercapacitor to buffer peak load, protect battery capacity and extend system life and performance. The full rechargeable supercapacitor helps buffer operation requires the energy required for components (such as those components in the electric smart lock).

For more details, as well as how to reduce the cost of the integrated programmable input current limit, see Application Guide: "Use input current limits to extend battery life."

Low output voltage ripple can improve reliability

The stability of the connection application is improved by reducing the output voltage ripple caused by a load transient. The ultra-fast transient response of the new buck-boost converter can maintain lower IQ while maintaining an internal conditioning loop. This feature is especially suitable for applications such as smart water meter and gas meter, but will consume a lot of power in a short time when sharing data.
