TPS61080DRCR – TEXAS INSTRUMENTS

The TPS61080DRCR is a highly integrated, 1.8V to 5.5V input, synchronous step-down converter from Texas Instruments, packaged in a tiny 6-pin WSON (WCSP-6) package. It features a fixed 1.2V output voltage with a maximum output current of 1A, making it ideal for powering low-power applications requiring a stable, regulated voltage. The device employs a constant-frequency, pulse-width modulation (PWM) control scheme with automatic power-saving features, including a light-load efficiency mode that minimizes quiescent current draw (typically 30µA). Its internal compensation circuitry simplifies design, eliminating the need for external components for stable operation. The TPS61080DRCR boasts high efficiency, typically exceeding 90% at moderate loads, which translates to reduced power dissipation and extended battery life in portable applications. Protection features include short-circuit, overcurrent, and thermal overload protection, enhancing system robustness. Common applications include powering microcontrollers, memory chips, and other low-power peripherals in battery-powered devices, wearables, and portable medical equipment where space and efficiency are paramount. The device’s small footprint and high efficiency make it a superior choice compared to larger, less efficient linear regulators.
