资 源 简 介
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).
