DESCRIPTION
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.
鈥?Wide-output Voltage Adjustment
