The TPS61085PWR is a high-performance, fully integrated boost converter from the reputable manufacturer Texas Instruments. This device is designed to efficiently step up voltage from a lower voltage source, making it ideal for battery-powered applications where extending runtime is crucial. It is housed in a compact TSSOP-14 (PWR) package, which allows for a small footprint on the PCB while maintaining excellent thermal performance.
Featuring a wide input voltage range from 1.8V to 6V, the TPS61085PWR is versatile enough to be used with various single-cell batteries, including Li-Ion, Li-Polymer, and NiMH. The output voltage is adjustable from 1.8V to 12.6V, which can be set using external resistors, providing flexibility to power a wide array of devices.
With an impressive efficiency of up to 96%, this boost converter minimizes energy loss during conversion, thereby maximizing battery life. It also supports a high switch current of up to 1.5A, which is sufficient for most portable electronics. The device operates at a fixed switching frequency of 600kHz, which provides a good balance between efficiency and component size, allowing the use of small inductors and capacitors.
The TPS61085PWR incorporates several protective features to ensure the longevity and reliability of the application. These include thermal shutdown, overvoltage protection, and a built-in soft-start function that prevents inrush current at startup. Moreover, it has under-voltage lockout (UVLO) to ensure the device operates only when sufficient voltage is present.
Applications for the TPS61085PWR are diverse and include products such as handheld devices, portable media players, and wireless peripherals. Its performance characteristics also make it well-suited for powering OLED displays and RF power amplifiers, which require higher voltages than those provided by standard batteries.
Texas Instruments provides comprehensive technical support for the TPS61085PWR, including detailed datasheets, reference designs, and simulation tools, making it easier for engineers to integrate this component into their designs and bring efficient, reliable products to market.
