TPS61032RSAR – TEXAS INSTRUMENTS

The TPS61032RSAR is a compact, high-efficiency synchronous step-down converter from Texas Instruments, packaged in a space-saving 6-pin SOT-23 package. It’s designed for applications requiring a low-quiescent-current, regulated output voltage from a relatively wide input voltage range of 1.8V to 5.5V. The device boasts a switching frequency of 1.2MHz, minimizing the size of external components. Output voltage is adjustable down to 0.8V via a single external resistor, allowing flexible voltage scaling. Typical efficiency exceeds 90% at light to moderate loads, making it ideal for battery-powered systems._x000D_

The integrated 100mA switch current and low 1.5µA shutdown current contribute to its extended battery life capabilities. The TPS61032RSAR incorporates features such as soft-start and overcurrent protection, enhancing system reliability. Common applications include powering low-power microcontrollers, sensor nodes, and other portable electronics where space and power efficiency are paramount. Its small size and high efficiency make it a superior choice compared to larger, less efficient linear regulators in similar applications, particularly in portable devices where minimizing power consumption is critical. The device’s internal compensation simplifies design, requiring minimal external components for stable operation.
