AVE600 Series

The AVE600 series half-brick isolated DC-DC converter provides a single regulated low noise 12 Vdc output that can deliver up to 50 amps. It has a wide 2:1 input range of 36 to 75 Vdc and is designed primarily for use with standard 48 V telecommunications equipment supplies. This converter is normally used in designs with a distributed power architecture (DPA), where one or more downstream non-isolated DC-DC converters meet the needs of lower voltage semiconductor devices.

Rated at 600 watts and with an ultra high conversion efficiency of 95.6%, the converter can operate over an ambient temperature range of -40 to 85˚C, continuing to deliver full power up to a baseplate temperature of 100˚C. The output voltage can be trimmed from 11.7 to 12.3 Vdc to meet a broad range of application needs and there is no minimum load requirement. The conversion technology employs 140 kHz fixed-frequency switching to help minimize external EMI filtering requirements.

Based on a high power density open-frame design that incorporates an aluminum thermal baseplate and is optimized for either conduction or forced air cooling, AVE600 series converters have an installed height of just 0.5 inch (12.7 mm), making them ideal for systems with demanding inter-board spacing requirements.

Standard features include input undervoltage lockout, remote On/Off and differential remote sense, as well as comprehensive protection against overtemperature and output overcurrent or overvoltage conditions.
