Product Overview: TPS61021ADSGR from Texas Instruments

The TPS61021ADSGR is a high-performance, synchronous boost converter that belongs to the expansive portfolio of power management integrated circuits (ICs) from Texas Instruments (TI). This device is designed to provide a flexible and efficient solution for products requiring a higher voltage from a lower voltage power source. It is particularly suitable for battery-powered applications where extending the battery life is crucial.

With an input voltage range of 0.8V to 5.5V, the TPS61021ADSGR is capable of supporting a wide array of power sources, from single-cell batteries to standard 3.3V or 5V power rails. The output voltage is adjustable from 1.8V to 12V, which allows designers to use the same part for multiple designs, simplifying inventory and reducing overall costs.

The efficiency of the TPS61021ADSGR is a key feature, with up to 96% efficiency through the use of synchronous rectification and a 1MHz fixed switching frequency. This high frequency enables the use of small, low-profile inductors and ceramic capacitors, which reduces the overall solution size and is ideal for space-constrained applications.

Additionally, the TPS61021ADSGR incorporates several protective features to ensure the longevity and reliability of the end application. These features include over-temperature protection, over-voltage protection, and under-voltage lockout. The device also offers a Power Save Mode for improved efficiency at light loads, further extending battery life in portable applications.

The TPS61021ADSGR is available in a small 2.0 x 2.0 mm, 8-pin WSON package, which is highly suitable for portable electronics such as smartphones, tablets, and IoT devices. Its compact size and high-density power conversion capabilities make it an excellent choice for designers looking to maximize performance in a minimal footprint.

Overall, the TPS61021ADSGR from Texas Instruments is a versatile and efficient solution for a wide range of power boosting applications. Its high efficiency, adjustable output voltage, and protective features make it an essential component for any power-sensitive design.
