AUG 20W Series
AUG 20W Ultra Low Profile DC – DC Module
(Pb-free reflow compatible and ROHS Compliant)
The AUG 20W series is Astec’s new Ultra Low Profile, 48Vin, SMT isolated single output modules. With the Ultra Low
Profile SMT design (only 4.8mm height), the module can be flexible mounted on the top side or the bottom side of
motherboard. The AUG 20W series also comes with enhanced features such as Remote on/off (RC), parallel Application
(PO), Power Good (ALM), and the protection of OVP, OCP and UVLO.

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