AEQ15AF48 - 5V/3.3V Dual Output DC-DC Converter Module

Industry Standard ¼ Brick w/ Baseplate: 36V-75V Input; 60W Output Power

The AEQ15 series is among Astec's dual output; high-density converter offering that comes in an industry standard ¼ brick

baseplate package. The AEQ15 series has been designed to deliver 60W of clean, well-regulated DC power for today's

demanding loads at high efficiency levels (89% typical for 30W/30W power split between rails). The 5V rail is capable of

delivering 12A max and the 3.3V rail is capable of delivering 15A max for a maximum output power of 60W. The module

comes with industry standard feature sets such as output enable with positive or negative logic options; input UVLO, output

trim, over current, over voltage and over temperature protection.
