TPS2069CDGNR – TEXAS INSTRUMENTS

The TPS2069CDGNR is a Texas Instruments single-channel, 4.5A synchronous buck converter in a compact, space-saving 6-pin WSON package. It operates from a 4.5V to 18V input voltage range, providing a highly efficient and adjustable output voltage, typically between 0.8V and 5.5V. This device utilizes internal MOSFETs, eliminating the need for external components and simplifying design. Its key feature is its integrated 60mΩ high-side and 30mΩ low-side MOSFETs, contributing to high efficiency, particularly at higher load currents. The TPS2069CDGNR features a programmable switching frequency (up to 1.5MHz), enabling designers to optimize EMI performance and component selection. Its internal soft-start minimizes inrush current, protecting the system from transient voltage spikes. Common applications include powering high-current peripherals in portable devices, efficient power supplies for embedded systems, and point-of-load converters requiring high efficiency and compact size. The device’s advantages lie in its high power density, ease of implementation, and robust protection features, making it a suitable choice where space is constrained and efficiency is paramount.
