Description
The new Q2S30 Series of single-output DC/DC converters offer unprecedented density and performance in
an industry-standard, quarter-brick footprint. Patent pending technology combined with state-of-the-art
packaging techniques allows the Q2S30 to provide 30A of output current in an 8.5mm package without a
heatsink. The 100% surface mount design provides consistent high quality and reliability, and the SMT
mounting option eliminates the need for separate (additional manual) operations to mount the converters to
the motherboards during mass production.
