DESCRIPTION

The SAT8565 is a non-isolated PowerPac module designed for high reliability and full military point of load

applications. Fully integrated, the SAT8565 includes buck controller, inductor, and input/output capacitors

integrated in a single package. The SAT8565 operates from an input voltage of +4.5V to +6V providing step

down power conversion to any output voltage from 1.21V to 5.0V. Operating features include output voltage

adjust, output current limit, shutdown, external synchronization and soft start. Careful design and layout ensure

excellent stability, transient response, and low noise operation. Packaged in a compact 5 Pin MO-078 package,

the SAT8565 is manufactured in a facility certified to MIL-PRF-38534 Class-H and operates over the full –

55^oC to +125^oC temperature range.
