Technical Reference Notes
ALQ15XX48X Series
(Open Frame Dual Output Quarter Brick)
ALQ15 Dual Output Open-Frame DC-DC Converter Module
Industry Standard ¼ Brick: 36V-75V Input / 60W Output Power
The ALQ15 series is Astec's latest dual output; high-density converter offering that comes in an industry standard ¼ brick
open-frame package. With its independently controlled output rails, the module effectively minimizes cross regulation, which
has been an issue to most dual converters available in the market. The ALQ15 series has been designed to deliver 60W of
clean, well-regulated, low noise DC power for today's demanding loads at respectable efficiency levels: 3.3V-2.5V
combination @ 87.5% (60W output power). Output combinations currently available are 5.0V/3.3V - 3.3V/2.5V - 3.3V/1.8V -
2.5V/1.5V, with each output rail able to deliver 15A max (5V@12A). The module comes with standard feature sets such as
output enable with positive or negative options; output voltage-adjust; over current, over voltage and over temperature
protection. In addition, it is also being offered at both 5mm (std) and 3.7mm pin lengths.
