General Description
The G5693 high-efficiency, DC/DC buck converter
delivers up to 3A of output current. The device oper-
ates from an input voltage of 2.5V to 5.5V and pro-
vides 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 fre-
quency minimizes the size of external components.
Internal soft-start control circuitry reduces inrush cur-
rent. Short-circuit and thermal-overload protections
improve design reliability.
The G5693 are available in a space-saving 8-pin SO
package.
