AEQ15AF48 Series
(Dual Output Quarter Brick - Baseplate)
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.
