Description

General part information

PTB48510C Series

The PTB4851x series of isolated DC/DC converter modules produce a complementary pair of regulated supply voltages for powering line-driver devices in xDSL telecom applications. The modules operate from a standard telecom (–48 V) central office (CO) supply and can provide up to a 72 W of power in a balanced load configuration.

The A-suffix module (±5 V) is designed to power the line driver devices for the AC-7 ADSL chipset. Other voltage options powers other analog applications requiring a complementary supply with relatively balanced loads.o

Both the PTB48510 and PTB48511 include an "on/off" enable control, output current limit, over-temperature protection, and input under-voltage lockout (UVLO). The PTB48511 adds output overvoltage protection (OVP).
