Delphi Series V48SB, 1/16th Brick Bus Converter
DC/DC Power Modules: 48Vin, 150W, 12Vo or 9.6Vo

The Delphi Series V48SB, 1/16 Brick sized, 48V input, single

th

output, fixed ratio bus converters are the latest offering from a world
leader in power systems technology and manufacturing — Delta
Electronics, Inc. This product features an input voltage range of 38V to
55V and provides up to 150 watts of power or up to 16A (9.6Vo) o
output current in an industry standard footprint and pinout. Both the 5:1
(9.6V) and 4:1 (12V) bus converters operate with constant output curren
from 38V to 55V input. Typical full load efficiency for both modules a
48Vin is up to 95.2%. This product represents the next generation o
design technology that supports the intermediate bus architecture to
power multiple downstream non-isolated point-of-load (POL) converters.
With creative design technology and optimization of componen
placement, these converters possess outstanding electrical and thermal
performance, as well as extremely high reliability under stressful
operating conditions. All modules carry a full set of international safet
approvals.
