PTB48580A Overview
The PTB48580 series of isolated DC/DC converter modules produce a plementary pair of regulated supply voltages for powering line-driver ICs in xDSL tele applications. The modules operate from a standard tele (-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 (±5 V) is designed to power the line driver ICs for the AC-7 ADSL chipset.
