Delphi Series L36SA, 2” x 1.6”, 50W Family
DC/DC Power Module: 18~75V in, 3.3V/15A out
The Delphi Series L36SA, 2” x 1.6”, 18~75V input, single output,
isolated DC/DC converter is the latest offering from a world leader in
power systems technology and manufacturing - Delta Electronics,
Inc. This L36SA series provides up to 50 watts of power or 15A of
output current (3.3V) in an industry standard 2” x 1.6” form factor
and pinout. The Delphi L36SA series operates from a wide 18~75V
(4:1) input voltages. With creative design technology and
optimization of component placement, these converters possess
outstanding electrical and thermal performances, as well as
extremely high reliability under highly stressful operating conditions.
All models are fully protected from abnormal input/output voltage,
current, and temperature conditions. The Delphi Series converters
meet all safety requirements with basic insulation. An optional heat
spreader is available for extended operation.
