DESCRIPTION
The DCT1048 family is a series of galvanically isolated
dc/dc converters designed for telecommunications
applications. With a low component count and highly
compact magnetics sets, the devices offer extremely
high power density in JEDEC standard with through-
hole and surface-mount IC packages. The unique
application of custom-level silicon integration, together
with an advanced thermal design, provides extremely
high reliability and allows operation at ambient
temperatures up to 85
°C.
The circuit provides isolation to 1500 VRMS, meeting the
requirements
of
UL1950/CSA22.2/EN
60950
(pending),
with
basic
insulation
to
75
V.
The
DCT10480x is a part of Texas Instrument’s range of
isolated dc/dc converters.
