DC/DC Power Modules:
36~75V in, 12V/2A out
The Delphi S36SE12002, 1x1 sized, 36~75Vin, single output, isolated
DC/DC converters are the latest offering from a world leader in power
systems technology and manufacturing — Delta Electronics, Inc. This
product is available in either a surface mount or through-hole package
and provides up to 25 watts of power or 12V/2A in a standard 1x1 form
factor (1.10”x0.96”). The pinout is compatible with the popular industry
standard 1x2 sized products. With creative design technology and
optimization of component placement, these converters possess
outstanding electrical and thermal performance, as well as extremely
high reliability under highly stressful operating conditions. The S36SE
12V module provides full output power without any airflow at over 80C
ambient
temperature
while
keeping
the
component
junction
temperatures under most derating guidelines. Typical efficiency of
12V/2A module is better than 87% and all modules are fully protected
from abnormal
conditions.
