TPS259261DRCT – TEXAS INSTRUMENTS

The TPS259261DRCT is a Texas Instruments single-channel, synchronous, 600mA step-down converter in a tiny 6-pin SOT-23 package. It operates from a 2.7V to 5.5V input voltage range and provides a highly efficient, adjustable output voltage down to 0.8V, making it ideal for applications requiring precise voltage regulation with minimal power loss. The device utilizes internal MOSFETs, eliminating the need for external components and simplifying design._x000D_

Key features include a 1.2MHz switching frequency enabling the use of smaller, less expensive inductors, and integrated soft-start for improved transient response. Its integrated protection circuitry encompasses short-circuit, over-current, over-temperature, and over-voltage protection, enhancing system reliability. The device’s low quiescent current (Iq) of typically 30µA contributes to extended battery life in portable applications._x000D_

Common use cases include powering low-power microcontrollers, sensor nodes, and other peripherals in battery-powered systems. Its small size and high efficiency make it particularly suitable for space-constrained designs where power optimization is crucial. The TPS259261DRCT’s robust protection features and ease of implementation significantly reduce design complexity and time-to-market. However, its relatively low output current limits its application to lower-power loads.
