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, soft start and under voltage lockout.

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, class H & K

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

Notes:

1. At this time, SatCon does NOT have a DSCC approved Radiation Program

2. Output Inhibit guaranteed @ Vshdn< 0.4V.

3. Shutdown input should be pulled up to Vin when not used.

4. Synch input should be grounded when not in use
