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.
