Description
The TPS62260DRVR is a high-efficiency, step-down DC-DC converter designed by Texas Instruments. It is part of the TPS6226x family and is optimized for portable and battery-powered applications. The device operates with an input voltage range from 2.0V to 6.0V, making it suitable for single-cell Li-ion batteries or other low-voltage sources.
This converter offers a fixed output voltage option and is capable of delivering up to 600 mA of output current. It features a typical efficiency of up to 95%, which is achieved through a combination of low-ripple Pulse Width Modulation (PWM) and power-saving modes. The TPS62260DRVR also includes an automatic transition between PWM and power-save mode to ensure efficiency across varying loads.
Other notable features include its small 2 mm x 2 mm QFN package, low quiescent current, and integrated soft start. These features make it ideal for space-constrained applications that demand high performance, such as smartphones, portable media players, and other handheld devices. Additionally, its protection features include short-circuit protection, thermal shutdown, and overcurrent protection.
