UL/cUL60950 Description Pin Configuration The PTB48580 series of isolated
DC/DC converter modules produce a
complementary pair of regulated supply
voltages for powering line-driver ICs in
xDSL telecom applications. The modules operate from a standard telecom
(-48 V) central office (CO) supply and
can provide up to a 30 W of power in a
balanced load configuration.
The A-suffix module (В±5 V) is designed
to power the line driver ICs for the AC-7
ADSL chipset. Other voltage options will …
