ALD Series

35 Watt Sixteenth-Brick Isolated DC-DC Converters

The ALD series of sixteenth-brick isolated DC-DC converters comprises seven single output models offering fully regulated voltages of 1.2 V, 1.5 V, 1.8 V, 2.5 V, 3.3 V, 5.0 V or 12.0 V. The 1.2 V and 1.5 V models can deliver up to 15 amps. These converters have a wide 2:1 input range of 36 to 75 Vdc and are designed primarily for use with standard 48 V telecommunications equipment supplies. Rated at 35 watts, they employ an open-frame construction, offer up to 91% efficiency and accommodate an ambient operating temperature range of -40 to 85˚C. The converters use fixed frequency switching to minimize the need for EMI filtering.

Standard features include output trim, remote enable, undervoltage lockout and differential remote sense. The converters offer up to 91% full load efficiency and are comprehensively protected against overvoltage, overcurrent and overtemperature conditions. ALD series converters have an installed height of just 0.34 inch (8.6 mm), making them ideal for systems with demanding inter-board spacing requirements.
