Delphi Series S24SA, 2”x1” Family
DC/DC Power Modules: 18~36Vin, 1.2V, 12A out
The Delphi Series S24SA, surface mountable, 24V input, single output,
isolated DC/DC converter is the latest offering from a world leader in
power system and technology and manufacturing -- Delta Electronics, Inc.
This product family provides up to 36 watts of power or up to 12A of
output current (for output voltage 1.8V or below) in a low profile 2”x1”
industry standard form factor and pinout. The S24SA operates from a
wide input range of 18V to 36V, output ranges from 1.2V to 12V. For 1.2V
at 12A full load, the efficiency is up to 85.5%. 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. All
models are protected from abnormal input/output voltage and current
conditions, and feature 2250V input/output isolation and basic insulation.
