Delphi S36SE, 17W 1x1 Brick Series
DC/DC Power Modules: 18~75V in, 3.3V/5A out
OPTIONS
The Delphi S36SE series, 1x1 sized, 18~75Vin, 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 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
(1.10”x0.96”x0.33”). 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 3.3V module could provide full output power
without any airflow up to 85°C ambient temperature while keeping the
component junction temperatures under most derating guidelines.
Typical efficiency of 3.3V/5A module is better than 86.5% and all
modules are fully protected from abnormal input/output voltage,
current, and temperature conditions.
