Delphi Series Q48SK, Quarter Brick Family
DC/DC Power Modules:
36~75V in, 12V/25A out, 300W
The Delphi series Q48SK12025, quarter brick, 36~75V 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 provides up to 300 watts of power in an industry standard footprint
and pin out. 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. The Q48SK12025 offers more than 95.2% high
efficiency at 25A full load. The Q48SK12025 is fully protected from abnormal
input/output voltage, current, and temperature conditions and meets all
safety requirements with basic insulation.

for Input Terminal Ripple Current and Input Reflected Ripple
Current.
Note: Measured input reflected-ripple current with a simulated
source Inductance (LTEST) of 12 µH. Capacitor Cs offset
possible battery impedance. Measure current as shown above.
