    Products Detail

    The PT4850 Excalibur™ power modules are a series of isolated triple-output 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 voltages for I/O and other functions. The series includes many features to simplify system integration, such as flexible On/Off enable control, input under-voltage lockout, and over-temperature protection. All outputs are current limited and short-circuit protected, and are internally sequenced to meet power-up and power-down requirements of popular DSP ICs.

    Key Features

    • Triple Logic Voltage Outputs, Dual Logic On/Off Control, Fixed Frequency Operation, Input Voltage Range: 36V to 75V, Solderable Space Saving Package, 1500VDC Isolation, Over-Current Protection, Over-Voltage Protection, Over-Temperature Shutdown, Under-Voltage Lockout, Independently Adjustable Outputs
