DATEL’s XHR Series DC/DC converters deliver a measure of cost-effective long­term reliability not previously available in commercial, off-the-shelf po wer converters.
These DC/DC’s combine the high-efficiency and wide-input-range of DATEL’s
venerable XWR Series DC/DC’s with a newly developed, all metal-ceramic, construc­tion technique that eliminates the need for thermally-conductive potting compounds.

All electrical components are surface-mount soldered to a 60 mil (0.06"/1.52mm)
ceramic baseplate for low junction-to-case thermal resistance. Package pins, instead
of traditional butt soldering, are soldered through the baseplate via pre-cut holes.
Pre-cutting prior to firing, as opposed to laser cutting after firing, eliminates micro
cracks. The tin plated, steel cover is soldered to the baseplate creating a level of
hermiticity not available in other commercial power modules. The bottom of the
baseplate has a conductive layer that provides 6-sided shielding. It is also insulated
so pc-card runs can pass beneath the package.

UHR Models are the single-output devices in the XHR Series. They offer outputs
of 3.3, 5, 12 or 15 Volts. The ultra-wide (4:1) input voltage ranges are either 9-36V
("D12" models) or 18-72V ("D48" models). Line and load regulation are a tight ±0.3%
max. and ±0.5% max., respectively. All devices guarantee that output ripple/noise will
be less than 100mVp-p. Isolation voltage is guaranteed to be at least 750Vdc.

UHR devices carry industry-standard pinouts in packages whose outside
dimensions are only slightly larger than the 2" x 2" standard. They can be subjected
to mutually-agreed-upon, high-rel screening programs as necessary to satisfy your
system's reliability requirements. Contact DATEL for additional details.
