Overview

Description

The TPS62840DLCR is a highly efficient, ultra-low power step-down DC-DC converter from Texas Instruments. Designed for applications requiring prolonged battery life, it operates with a wide input voltage range from 1.8V to 6.5V, making it suitable for both single-cell and multi-cell battery configurations. The device delivers a fixed output voltage with high efficiency across various load conditions, thanks to its DCS-Control™ topology.
One of its standout features is the ultra-low quiescent current of just 60 nA, which significantly enhances battery longevity in power-sensitive applications. The TPS62840DLCR supports a load current of up to 750 mA and offers a selectable power-save mode for improved efficiency during light-load conditions. Other features include an adjustable output voltage via external resistors, a precise enable threshold, and robust protection mechanisms like output short-circuit protection and thermal shutdown.
Its compact size, combined with high efficiency and low power consumption, makes the TPS62840DLCR ideal for wearable devices, IoT applications, and any portable electronics where space and battery life are critical constraints.
