ALD18 General Description


The ALD12/18/20/25 series is Astec's latest 16th Brick industry standard offering. Operating from an input voltage range of 36V to 75V, the series provides 6 configured outputs from 1.2V all the way up to 5V. It delivers up to 25A max current for 1.8V and lower at impressive levels of efficiency. The series comes with industry standard features such as Input UVLO; non-latching OCP, OVP and OTP; Output Trim; Differential Remote Sense pins. With its wide operating temperature range of -40°C to 85°C ambient, the converters are deployable into almost any environment.

ALD18 Maximum Ratings

Stresses in excess of the absolute maximum ratings can cause permanent damage to the converter. Functional operation of the device is converter is not implied at these or any other conditions in excess of those given in the operational section of the specs. Exposure to absolute maximum ratings for extended period can adversely affect device reliability.
