Texas Instruments presents the TPS6290x series, a family of highly efficient and versatile synchronous step-down DC/DC converters specifically designed for applications in factory and building automation. These converters provide reliable power solutions with their advanced features and flexible operation.
The TPS6290x series offers a compact form factor and is easy to use. It features a selectable switching frequency of either 2.5 MHz or 1.0 MHz, allowing the use of small inductors and providing fast transient response. This ensures efficient power delivery and stable performance in various operating conditions.
With the DCS-Control™ topology, the TPS6290x series achieves a high VOUT accuracy of ±1%. This precision enables precise voltage regulation, ensuring consistent and reliable power supply to the connected devices or systems. The wide input voltage range of 3 V to 17 V supports a variety of nominal inputs, including 12 V supply rails, single-cell or multi-cell Li-Ion batteries, and 5 V or 3.3 V rails. This versatility makes the TPS6290x series suitable for a wide range of automation applications.
One of the key features of the TPS6290x series is its ability to automatically enter power-save mode when light loads are detected, thus maintaining high efficiency. If auto PFM/PWM (Pulse Frequency Modulation/Pulse Width Modulation) is selected, the converter can achieve this while consuming a typical quiescent current of only 4 µA. This feature helps optimize power consumption and extends battery life in battery-powered applications.
To further enhance usability and minimize solution size, the TPS6290x series includes a multi-function MODE/Smart-CONF pin. This pin allows users to set various parameters such as the internal or external divider, switching frequency, output voltage discharge, and automatic power-save mode or forced-PWM (Pulse Width Modulation) operation. This flexibility simplifies the design process and enables customization to meet specific application requirements.
In summary, Texas Instruments' TPS6290x series offers highly efficient and flexible DC/DC converters tailored for automation applications in factory and building automation. With their wide input voltage range, selectable switching frequencies, high VOUT accuracy, and power-saving capabilities, these converters provide reliable and optimized power solutions. The inclusion of the multi-function MODE/Smart-CONF pin enhances usability and customization options, making them suitable for a variety of automation scenarios.
