(Single Output 8^th Brick)
AEO/ALO Single Output 8^th Brick: Baseplate or Open-Frame Module
The AEO_ALO04/12/20/25x48 series is Astec’s Low Current 8^th Brick industry standard offering. Operating from an input
voltage range of 36V to 75V, the series provides 7 configured outputs starting from 1.2V all the way up to 12V. It delivers up
to 25A max current for 1.8V and lower voltages at impressive levels of efficiency. It provides tight regulation and exhibits
clean and monotonic output start up characteristics. The AEO_ALO series comes with industry standard features such as Input
UVLO; non-latching OCP, OVP and OTP; Output Trim; Differential Remote Sense pins. Both baseplate (AEO) and open
frame (ALO) construction are available as well as TH and SMT termination. With its wide operating temperature range of
-40°C to 85°C ambient, the converters are deployable into almost any environment.
