PTB48600A 85W 双路互补输出 DC/DC 转换器

PTB48600A 描述

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. It will also power any other applications that require a complementary supply with relatively balanced loads. The two compliementary outputs can also be configured as a single output of twice the voltage magnitude. As an example, the outputs of a PTB48600A can be adjusted up to ±6 V, and configured as a single 12-V output
