82.5 Watt Half-Brick Isolated DC-DC Converters
The AGH100 series half-brick isolated DC-DC converter provides a single regulated low noise 3.3 Vdc output. 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. Rated at 82.5 watts, the converter can deliver up to 25 amps and accommodates a wide ambient operating temperature range of -40 to 85˚C.
Offering a very high typical efficiency of 92.4%, the converter is based on an open-frame design that is optimized for forced air or conduction cooling – an aluminium baseplate option is available for enhanced thermal performance. The conversion technology employs 270 kHz fixed frequency switching to help minimize external EMI filtering requirements.
Standard features include input undervoltage lockout, remote enable, differential remote sense and output trim, with non-latching overvoltage, short-circuit and overtemperature protection. AGH100 series converters have an installed height of just 0.39 inch (10 mm), making them ideal for systems with demanding inter-board spacing requirements.
