TPS62063DSGT – TEXAS INSTRUMENTS

The TPS62063DSGT is a Texas Instruments synchronous step-down converter housed in a tiny 6-pin SOT-23 package. It’s designed for applications requiring high efficiency in a space-constrained environment, operating from a 1.8V to 5.5V input voltage range. This device features a fixed 3.3V output voltage with a maximum output current of 600mA, making it suitable for powering various low-power digital circuits and peripherals. The internal synchronous rectification minimizes power loss, achieving efficiencies exceeding 90% at typical loads. Its switching frequency is internally fixed at 1.2MHz, simplifying external component selection and minimizing EMI concerns. The TPS62063DSGT incorporates features such as soft-start, overcurrent protection, and thermal shutdown, enhancing system reliability. Common use cases include powering microcontrollers, memory chips, and sensor nodes in portable devices, wearables, and battery-powered equipment where high efficiency and small form factor are paramount. Its advantages lie in its compact size, high efficiency, and integrated protection mechanisms, simplifying board layout and reducing the overall bill of materials. Note the fixed output voltage limits its application to systems requiring a regulated 3.3V supply.
