TPS62111RSAT – TEXAS INSTRUMENTS

The TPS62111RSAT is a highly integrated, synchronous step-down converter from Texas Instruments, packaged in a space-saving 6-pin WSON (WCSP-6) package. It operates from a 2.5V to 5.5V input voltage range and provides a highly efficient, adjustable output voltage typically ranging from 0.8V to 5V, configurable via an external resistor divider. This device features a switching frequency of 1.2MHz, minimizing the size of external components. Internal compensation simplifies design, reducing external component count and board space. The TPS62111RSAT incorporates features like a soft-start function to minimize inrush current and a power-good output signal for system monitoring. Its high efficiency, typically exceeding 90%, makes it ideal for applications requiring low power consumption, such as portable devices, battery-powered systems, and always-on sensors. Its small size and ease of use are key advantages for space-constrained designs. The device’s ability to handle input voltages up to 5.5V provides design flexibility, accommodating a wider range of input sources. However, designers should note the limitations on output current, typically around 1A, depending on input voltage and output voltage setting.
