📥 Download Datasheet

General 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 balanced load configuration.

The A-suffix module (±5 V) is designed to power the line driver ICs for the AC-7 ADSL chipset.
