The YNC12S20 non-isolated DC-DC converter delivers up to 20 A of output current in an industry-standard
surface-mount package. Operating from a 9.6 to 14 VDC input, the YNC12S20 converter is an ideal choice
for Intermediate Bus Architectures where point-of-load power delivery is generally a requirement. It provides a
resistor-programmable regulated output voltage of 0.7525V to 5.5V.
The Y-Series converters provide exceptional thermal performance, even in high temperature environments
with minimal airflow. This is accomplished through the use of circuit, packaging and processing techniques to
achieve ultra-high efficiency, excellent thermal management and a very low body profile.
The low body profile and the preclusion of heat sinks minimize impedance to system airflow, thus enhancing
cooling for both upstream and downstream devices. The use of 100% automation for assembly, coupled with
advanced power electronics and thermal design, results in a product with extremely high reliability.
