The YNS05S10 converter is not recommended for new designs and has been replaced by the
YS05S10. Please refer to the YS05S10 data sheet for new product specifications.
Bel Power Solutions point-of-load converters are
recommended for use with regulated bus converters in an
Intermediate Bus Architecture (IBA). The Y-Series of non-
isolated dc-dc converters deliver up to 10 A of output
current in an industry-standard surface-mount package.
Operating from a 3.0 to 5.5 VDC input, the YNS05S10
converters are ideal choices for Intermediate Bus
Architectures where Point-of-Load (POL) power delivery is
generally a requirement. The converters provide an
extremely tight regulated programmable output voltage
from 0.7525 to 3.63 VDC.
RoHS lead free and lead-solder-exempt products
are available
The Y-Series of converters provide exceptional thermal
performance, even in high temperature environments with
Delivers up to 10 A (36 W)
No derating up to 85 C
Surface-mount package
Industry-standard footprint and pinout
Small size and low-profile: 1.30” x 0.53” x 0.314”
(33.02 mm x 13.46 mm x 7.98 mm)
without airflow at natural convection. This performance is
accomplished through the use of advanced circuitry,
packaging, and processing techniques to achieve a design
possessing 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.
