Technical Reference Notes
AEH/ALH80 Series
AEH/ALH80 Single Output Baseplate/Open-Frame DC-DC Converter Module
Industry Standard ½ Brick: 36V-75V Input / 80A Output Current
The AEH/ALH80 series is part of Astec's next generation single output, high-density industry standard half bricks. It operates
from a 36V to 75V DC Bus and comes in three different Isolated Logic Output voltages (ILO) well suited for DPA
applications. It’s designed to handle 80A maximum output current for 1.8V, 1.5V and 1.2V at high levels of efficiency. It
provides tight regulation and exhibits clean and monotonic output start up characteristics. The AEH/ALH80 comes with
industry standard features such as Input UVLO, OCP, OVP, OTP, output Trim, differential output Sense pins. It comes either
with baseplate or open frame construction, with double pair or single pair (option) output pins.
