Description
Power-One’s point-of-load converters are recommended for use with regulated bus converters in an
Intermediate Bus Architecture (IBA). The YNS12S16 non-isolated DC-DC converters deliver up to 16A of
output current in an industry-standard surface-mount package. The YNS12S16 converters operate from a
9.6-14 VDC input. These converters are ideal choices for Intermediate Bus Architectures where Point-of-Load
power delivery is generally a requirement. They provide a resistor-programmable regulated output voltage of
0.7525 V to 5.5 V.
The YNS12S16 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 heatsinks 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.
