Module DC-DC 2-OUT 15V 1.5A 45W 21-Pin SIP Module

The PT4711 Excalibur power module is a 45-watt rated DC/DC converter that produces two regulated output supply voltages from a standard (–48 V) telecom central office supply. Both of the outputs from this module are truly independent. Each is separately regulated and has its own negative return. This allows the flexibility of configuring the output for up to three voltage options. This includes a complimentary dual ±15-V, or a single +30-V or –30-V output. The PT4711 incorporates many features to simplify system integration. These include a flexible On/Off enable control, input under-voltage lock-out, and over-temperature protection. All outputs are short-circuit protected, and internally sequenced for simultaneous power-up and power-down. The module is packaged in a space-saving solderable copper case, requires no heat sink, and can occupy as little as 1.2 in² of PCB area.
