Description
The PTB48600A is one of a series
of isolated DC/DC converter modules
that provide a pair of complementary
supply voltages for powering line-driver
ICs in xDSL telecom applications. These
modules operate from a standard telecom
(-48 V) central office supply and can
provide up to a 85 W of power in a bal-
anced load configuration.
The A-suffix module (±5 V) is designed
to power the line driver ICs for the AC-7
ADSL chipset. It will also power any
other applications that require a comple-
mentary supply with relatively balanced
loads. The two compliementary outputs
can also be configured as a single output
of twice the voltage magnitude. As an
example, the outputs of a PTB48600A
can be adjusted up to ±6 V, and config-
ured as a single 12-V output.
The PTB48600 includes an output
“on/off” enable control, output current
limit, over-temperature protection, and
input under-voltage lockout (UVLO).
The control inputs, “Enable” and
“Sync In,” are compatible with the “EN
Out” and “Sync Out” signals of the
PTB4850x DC/DC converter. This
allows the power-up and switching fre-
quency of a PTB48600 module to be
directly controlled from a PTB48500.
Together the PTB48500 and PTB48600
converters meet all the system power
and sequencing requirements of the AC-7
ADSL chipset.
The PTB48600 employs double-sided
surface mount construction. The pack-
age options include both through-hole
and surface mount pin configurations.
