Q2S SERIES

The Q2S DC/DC converters offer unprecedented performance in the

industry-standard Quarter Brick format. This is accomplished through

the use of patent pending circuit and packaging techniques to achieve

ultra-high efficiency, excellent thermal performance and a very low

profile. The Q2S 30 A modules provide exceptional thermal

performance. The low profile (<0.30") of the modules and no need for

a heatsink minimize airflow shadowing, which enhances cooling for

downstream devices.

The use of 100% surface-mount technologies for Q2S assembly,

coupled with advanced electronic circuitry and thermal packaging,

result in products with extremely high quality and reliability. Q2S

converters are available as surface-mountable and through-hole

modules, in five standard output voltages ranging from 3.3 V to 1.5 V.
