TPS62112RSAR – TEXAS INSTRUMENTS

The TPS62112RSAR is a highly efficient, synchronous step-down converter from Texas Instruments, packaged in a space-saving 6-pin SOT-23. It’s designed for applications requiring a low-quiescent current (Iq) and precise output voltage regulation. Operating from an input voltage range of 1.8V to 5.5V, it delivers a regulated output voltage adjustable from 0.8V to V_IN – 0.3V, making it ideal for powering sensitive low-voltage circuitry from a higher voltage source. The device utilizes a pulse-width modulation (PWM) control scheme with internal compensation, simplifying external component selection._x000D_

Its key features include a maximum output current of 150mA, making it suitable for powering microcontrollers, sensors, and other low-power peripherals. The device boasts a high switching frequency of up to 1.2MHz, minimizing the size of external inductors and capacitors. Low Iq of typically 20µA contributes to significantly extended battery life in portable applications. The TPS62112RSAR integrates soft-start functionality to prevent inrush currents and features overcurrent and thermal protection, enhancing system robustness. Its small footprint and high efficiency make it a preferred choice for space-constrained portable and battery-powered devices where high efficiency and low quiescent current are critical design parameters.
