TPS22966DPUR – TEXAS INSTRUMENTS

The TPS22966DPUR is a single-channel, 4A synchronous buck converter from Texas Instruments, packaged in a space-saving 16-pin WSON package. It operates from a wide input voltage range of 4.5V to 18V, efficiently regulating output voltage down to a minimum of 0.8V. Featuring a 100kHz switching frequency, it minimizes external component size while maintaining high efficiency, typically exceeding 90% at moderate loads. The device incorporates internal compensation, simplifying design and reducing the external component count. Its key features include overcurrent protection, overvoltage protection, and thermal shutdown, ensuring robust operation and preventing damage in fault conditions._x000D_
