70-W Quad-Output DC/DC Converter For DSL

The PT4741 Excalibur power module is a 70-watt quad-output DC/DC converter that is designed to meet the power requirements of Texas Instruments TNETD7112. The TNETD7112 is a dual-channel line-interface driver/receiver that compliments the AC6 ADSL chipset for use in POTS (plain old telephone service) applications. To conserve power, the TNETD7112 Line Drivers require two pairs of complimentary power supply voltages. These are 8V and 3.75V respectively. The PT4741 module operates from a standard (48V) telecom central office supply and provides all four supply voltages as two com- plimentary balanced loads. (This product is not suitable for unbalanced load applications.) The load capacity allows the PT4741 to operate up to 32 line-driver ICs, representing 64 ADSL channels. The PT4741 incorporates many features to simplify system integra- tion. These include a flexible On/Off enable control, input under-voltage lock-out, and over-temperature pro- tection. All outputs are short-circuit protected, and internally sequenced to meet the TNETD7112 power-up and power-down requirements. The module is packaged in a space-saving solderable copper case, requires no heat sink, and CAN occupy as little as 1.9 in2 of PCB area. By Texas Instruments
