General Description
The G5693 high-efficiency, DC/DC buck converter delivers up to 3A of output current. The device operates from an input voltage of 2.5V to 5.5V and provides an output voltage from 0.8V to VIN, making the G5693 ideal for on-board post-regulation applications. The G5693 operate at a fixed frequency of 1MHz 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 G5693 are available in a space-saving 8-pin SO
package.
