TPS62933DRLR – TEXAS INSTRUMENTS

The TPS62933DRLR is a 3.3V, 300mA synchronous step-down converter from Texas Instruments, packaged in a tiny 6-pin WSON (WCSP-6) package. It’s optimized for low-power applications requiring a regulated 3.3V output from a wide input voltage range of 2.7V to 5.5V. Its key feature is its high efficiency, achieving up to 95% at light loads, crucial for battery-powered devices. The device incorporates internal compensation, simplifying design and reducing external component count. It features a programmable switching frequency (up to 2.2MHz), allowing designers to optimize EMI performance and board layout flexibility. The TPS62933DRLR utilizes a synchronous architecture, minimizing power loss during both switching transitions. Typical applications include powering low-power microcontrollers, sensors, and other peripherals in portable devices, wearable electronics, and IoT gadgets. Its small size and high efficiency make it ideal for space-constrained and power-sensitive designs where minimizing external components is paramount. The device also includes features such as soft-start and overcurrent protection for robust operation.
