DESCRIPTION
The BBF2800S series of DC-DC converters provides the
ruggedness, reliability and features required to meet the
advanced design challenges of today’s hi-rel market. This has
been accomplished using a package having very low thermal
gradients, excellent hermeticity and high voltage isolation.
The use of advanced substrate and reflow soldering tech-
niques 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 tolerant 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.
