Description

The PT4850 Excalibur™ power modules are a series of isolated tripleoutput DC/DC converters that operate from a standard (48V) central office supply. These modules are rated for a combined output of up to 25A, and were designed for powering mixed logic applications.

The triple-output voltage provides a compact multiple-output power supply in a single DC/DC module.

Output voltage options include a low-voltage output for a DSP or ASIC core, and two additional supply voltages for the I/O, and other functions.

The PT4850 series incorporates many features to simplify system integration. These include a flexible On/Off enable control, input undervoltage lockout and over-temperature protection. All outputs are current limited and short-circuit protected, and are internally sequenced to meet the power-up and power-down requirements of popular DSP ICs.

The PT4850 series is housed in a space-saving solderable case. The module requires no external heat sink. Both vertical and horizontal pin configurations are available, including surface mount.
