ALD 35W Series
Active
35 W Sixteenth-Brick Isolated DC-DC Converters
Get comprehensive protection against overvoltage, overcurrent, and overtemperature conditions with our ALD series of sixteenth-brick isolated DC-DC converters. The series is composed of 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. Suited for use with standard 48 V telecommunications equipment supplies, these 35 W DC-DC converters have a wide 2:1 input range of 36 to 75 VDC.
These converters employ an open-frame construction and use fixed-frequency switching to minimize the need for EMI filtering while operating at an ambient temperature of -40 to 85˚C. Providing up to 91% efficiency at full load, the converters have an installed height of just 0.34 inch–making them ideal for systems with demanding inter-board spacing requirements.
Standard features include output trim, remote enable, undervoltage lockout, and differential remote sense.
