TPS62740DSSR – TEXAS INSTRUMENTS

The TPS62740DSSR is a highly integrated, 2.8V to 5.5V input, synchronous step-down converter from Texas Instruments, packaged in a space-saving 6-pin WSON (WCSP-6) package. It features a fixed 1.8V output voltage and delivers up to 1A of continuous output current, making it ideal for powering voltage-sensitive peripherals in portable applications. Its internal synchronous rectification topology ensures high efficiency, typically exceeding 90% at a 3.3V input and 1A load, minimizing power loss and extending battery life. The device incorporates features such as soft-start, short-circuit protection, and thermal overload protection, enhancing system reliability. The TPS62740DSSR’s small footprint and high efficiency are particularly advantageous in space-constrained designs, such as wearables, mobile devices, and battery-powered IoT sensors requiring a stable 1.8V supply from a fluctuating input voltage. Its fixed output voltage simplifies design, eliminating the need for external voltage adjustment components and reducing the overall bill of materials. The device’s internal compensation further streamlines design, requiring minimal external components for stable operation.
