GHP2815S
HYBRID-HIGH RELIABILITY
RADIATION HARDENED
DC-DC CONVERTER
120W, Single Output
Description
The GHP2815S is a low voltage 15V/8A single output DC-DC
converter. It is specifically designed in response to the
need for moderate power, high efficiency and tight regulation
required by modern day space design applications. This
radiation hardened, high reliability converter is designed for
extended operation in hostile environments. Its small size
and low weight makes the GHP2815S ideal for applications
such as geostationary earth orbit satellites and deep space
probes. It exhibits a high tolerance to total ionizing dose,
single event effects and environmental stresses such as
temperature extremes, mechanical shock, and vibration.
All components are fully de-rated to meet the requirements
of MIL-STD-975, MIL-STD-1547 and GSFC PPL-21 Appendix B.
The design incorporates a fixed frequency topology with
magnetic feedback. Incorporation of many functional features
including external inhibit, output remote sensing, under-voltage
lockout and synchronization makes this device suitable for
today’s space design applications.
The converter is enclosed in a hermetically sealed package
with the overall dimensions of 3.50"L x 2.50”W x 0.475"H
including the I/O pins and mounting tabs. The base material
is aluminum-silicon-carbide. The lid material is Kovar. The
I/O pins are rugged ceramic feed-through copper core
Alloy 52. The lid is seam sealed using parallel seam welding.
A complete GHP2815S converter weighs 110 grams maximum.
Manufactured in a facility fully qualified to MIL-PRF-38534,
these converters are fabricated utilizing DLA qualified processes.
