Delphi S48SE, 17W 1x1 Brick Series
DC/DC Power Modules: 48V in, 5.0V/3A out
The Delphi S48SE series, 1x1 form factor, 48V input, 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 family is available in either a surface mount or
through-hole package and provides up to 17 watts of power or 5A of
output current (3.3V and below) in a standard 1x1 form factor
(1.1”x0.96”x0.33”). The pinout is compatible with the industry
standard 1x2 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. Typical
efficiency of 5.0V/3A module is better than 87% and all modules are
fully protected from abnormal input/output voltage, current, and
temperature conditions.
