BBF2800S

DESCRIPTION:

The BBF2800S series of DC-DC converters provides the ruggedness, reliability and features required to

having very low thermal gradients, excellent hermeticity and high voltage isolation. The use of advanced substrate

and reflow soldering techniques during construction results in a rugged, cost-effective pin solderable package.

The BBF2800S hybrid converter series utilizes all ceramic capacitors and surface mount magnetics to provide

reliable operation at all operating temperatures while surviving very high G forces.

BBF2800S series standard features include kelvin sense, indefinite short circuit protection, remote shutdown,

output fault monitoring, turn on voltage point adjustment, switching frequency synchronization of up to 3 units using

no external components and pi-network input filtering. An output voltage adjustment/load compensation pin is also

standard.

Fault tolerance design protects these converters from most external circuit faults. The output and output adjust

pins will withstand +35V while the shutdown and all synchronization pins will withstand +50V protecting the

converters from a variety of system or board faults, i.e. solder bridges, etc. Unique load fault protection circuitry

allows this converter to pull up loads having difficult static load line characteristics and allows short term load

excursions significantly beyond ratings in most applications.

The BBF2800 series is a current mode push-pull topology converter which operates at a switching frequency of

500KHz. Internal filtering of both input and output eliminates the need for external capacitors in many applications.

The 12-pin power dip package allows connection to a heatsink and is hermetically sealed and isolated from the

internal circuits.
