Technical Reference Notes

ALD12/18/20/25 Series

(Single Output 16

Brick)

ALD12/18/20/25 Single Output 16

Brick: 60Watts

The ALD12/18/20/25 series is Astec’s latest 16

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.
