概要

Description

The TPS62746YFPR is a highly efficient, step-down DC-DC converter designed by Texas Instruments, tailored for battery-powered applications. It features a wide input voltage range from 1.8V to 5.5V, making it suitable for various low-voltage power sources. With a low quiescent current (typically around 1.2 µA), it is optimized for ultra-low power consumption, which extends battery life in portable devices.
The device offers a fixed output voltage option (typically 1.2V, 1.5V, or 1.8V) and supports a high efficiency of up to 95%, especially in light load conditions. This is achieved through its unique Power Save Mode, which maintains efficiency during low power operations.
Additionally, the TPS62746YFPR includes features such as overcurrent protection, thermal shutdown, and a compact QFN package, making it suitable for space-constrained applications. It is commonly used in IoT devices, wearables, and other battery-operated electronics where efficiency and small size are critical.
