DESCRIPTION

The SAT8564 is a non-isolated PowerPac module for high reliability and full military distributed power, point

of load applications. Fully integrated, the SAT8564 includes buck controller, inductor, and input/output

capacitors integrated in a single package. The SAT8564 operates from an input voltage of +4.5V to +12V

providing step down power conversion to output voltages as low as 1.21V. Operating features include output

voltage adjust, output current limit, shutdown, external synchronization and soft start. The SAT8564 can also

be set up in a parallel configuration to increase output current capability.

Careful design and layout ensure excellent stability, transient response, and low noise operation. Packaged in a

compact 16-lead flat-pack the SAT8564 is manufactured in a facility certified to MIL-PRF-38534 and operates

over the full –55^oC to +125^oC temperature range.

Notes:

1. Output Inhibit guaranteed @ Vshdn< 0.4V. Shutdown not available in SAT8564P.

2. Shutdown input should be pulled up (Rpullup ≤ 5KΩ) to Vin when not used.

3. Synch input should be grounded when not in use
