General Description
The AT1529 high-efficiency, DC/DC buck converter delivers up to 3.2A of output current. The device operates from an input voltage of 2.5V to 6V and provides an output voltage from 0.8V to VIN, making the AT1529 ideal for on-board post-regulation applications.
The AT1529 operate at a fixed frequency of 1MHz with an efficiency of up to 94%. The high operating frequency minimizes the size of external ponents. Internal soft-start control circuitry reduces inrush current. Short-circuit and thermal-overload protections improve design reliability.
The AT1529 are available in a space-saving SOP-8 and TDFN3X3-8 package.
