Product Overview: TPS61140DRCT from Texas Instruments

The TPS61140DRCT is a high-performance, adjustable, monolithic, step-up converter with an integrated 1.5-A switch from Texas Instruments. Designed for systems that require power efficiency and a compact footprint, this device is ideal for battery-powered applications. It operates over a wide input voltage range from 2.7 V to 6 V, making it suitable for products powered by single-cell Li-Ion batteries, as well as by multiple-cell battery configurations and regulated 5V supplies.

The TPS61140DRCT offers a flexible and robust power solution with features such as a fixed or adjustable output voltage up to 38 V, which is set by external resistors. Its high switching frequency, which is typically 1.2 MHz, allows the use of small external components, thereby reducing the overall solution size. The device also incorporates a soft-start feature that limits inrush current during startup, providing a smooth power-up sequence for sensitive electronics.

This converter is designed with efficiency in mind, featuring a low quiescent current and entering power-save mode at light load conditions, which further extends battery life in portable applications. Additionally, the TPS61140DRCT includes over-temperature and over-current protection, enhancing system reliability and safety.

The integration of such protections makes the TPS61140DRCT a reliable choice for powering LEDs, OLED displays, and other high-voltage bias supplies. Its small 10-pin DRC package is optimized for space-constrained applications, and the device is characterized for operation over the free-air temperature range of –40°C to 85°C.

In summary, the TPS61140DRCT by Texas Instruments is a versatile and efficient solution for designers looking to maximize power management in compact, battery-driven electronics. Its combination of high efficiency, adjustable output voltage, and integrated protections make it a robust choice for a wide array of applications.
