3A Synchronous Rectified Step Down Converter
XT1720
■ General Description
■ Features
The XT1720 is a monolithic synchronous high-efficiency DC/DC buck converter delivers up to 3A of output current. The device operates from an input voltage of 2.5V to 8 V and provides an output voltage from 0.8V to VIN, making the XT1720 ideal for on-board post-regulation applications. The XT1720 operate at a wide switching frequency range from 300KHz to 1.5MHz with an efficiency of up to 94%. The high operating frequency minimizes the size of external components. Internal soft-start control circuitry reduces inrush current. Short-circuit and thermal-overload protections improve design reliability. The XT1720 are available in a space-saving SOT-23-6 package.
