MHP8564

(Formerly SAT8564 Series)

(Consult Table 3 for Part Number Designations)

Levels Available

MHP8564

COTS

SINGLE 4 Amp POINT-OF-LOAD REGULATOR

MILITARY

SPACE

DESCRIPTION

The MHP series are non-isolated Point of Load switching regulators for high reliability

Military and Space distributed power applications. Fully integrated, these include a

buck controller, inductor, and input / output capacitors combined in a single package.

They operate from an input voltage of +4.5V to +5.5V (See Note 1), providing step

down power conversion to output voltages as low as 0.5V or lower (See Note 2).

Operating features include output voltage adjust, output current limit, enable, external

synchronization and soft start. Some models can also be setup in a parallel

configuration to increase output current capability and reduce ripple on the input and

output supplies. Careful design and layout ensure excellent stability, transient

response, and low noise operation. Packaged in a compact metal case, it operates

over the full -55°C to +125°C temperature range.
