Overview

The TPS62A01DRLR is a high-frequency synchronous step-down buck regulator capable of delivering up to 1A of output current. It operates with a high 2.4MHz switching frequency, allowing for the use of small external inductors and capacitors to minimize the total solution footprint. With a wide input voltage range of 2.5V to 5.5V and a low 20uA quiescent current, it is optimized for efficiency in battery-powered applications.

Why Choose This Part

This regulator offers high precision with 1% feedback accuracy across a wide temperature range and includes a 100% duty cycle mode for very low dropout operation. Integrated features like internal soft start, hiccup-mode short-circuit protection, and active output discharge simplify circuit design while improving system reliability.

Applications

Point-of-Load Regulation
Efficiently stepping down 3.3V or 5V rails to lower core voltages for MCUs, FPGAs, and DSPs.
Battery-Powered IoT Devices
Utilizing the 20uA quiescent current and power-save mode to extend operating life in portable electronics.
Space-Constrained Wearables
Leveraging the tiny SOT-563 package and 2.4MHz frequency to reduce PCB area requirements.
