PTB48510B 72W +/-12V 双路互补输出 DC/DC 转换器

PTB48510B 描述

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).
