TPS2113ADRBR – TEXAS INSTRUMENTS

The TPS2113ADRBR is a Texas Instruments single-channel, 4A synchronous buck converter in a tiny 10-pin, 3x3mm QFN package. It’s designed for high-efficiency power conversion in space-constrained applications, boasting a typical efficiency exceeding 90% at 3A load. Operating from an input voltage range of 2.7V to 5.5V, it provides a highly adjustable output voltage, programmable via an external resistor divider, typically ranging from 0.8V to 5V. The device incorporates internal compensation, simplifying design and reducing component count. Its key features include a 100kHz switching frequency, soft-start functionality to minimize inrush current, and overcurrent/overtemperature protection ensuring robust operation. The TPS2113ADRBR excels in portable devices requiring efficient power delivery to low-voltage loads such as microprocessors, memory, and other integrated circuits. Its small size and high efficiency make it ideal for battery-powered systems where minimizing power loss and board space are critical design considerations. The device’s internal MOSFETs eliminate the need for external switching elements, further streamlining the design process.
