RT5721 Overview
The RT5721 is a step-down switching voltage regulator that delivers a digitally programmable output from an input voltage supply of 2.5V to 5.5V. The output voltage is programmed through an I2C interface capable of operating up to 3.4MHz. Using a proprietary architecture with synchronous rectification, the RT5721 is capable of delivering 1A continuously at over 80% efficiency, maintaining that efficiency at load...
