The Delphi D12s1r845d, Surface Mounted, Power Block Is The Latest Offering From A World Leader In
Power Systems Technology And Manufacturing - Delta Electronics The D12s1r845d Is The Latest Offering
In The Dxp45 Family Which Was Developed To Address The Ever-growing Demands Of Increased Current And
power densities in networking
Applications While Providing Maximum Flexibility For System Configuration, Its Benefits Can Easily
be applied to other
Applications Transcending Various Market Segments. The Dxp45 Family, Containing All Necessary Power
Components And Boasting Of A Usable (55 C, 200lfm) Current Density Of 90a/in2 And A Power Density
Of Up To 231w/in3, Is A Building Block For A New Open Digital Power Architecture Developed To Work
With Either Digital Or Analog Controllers. Measured At 0.5"wx1.0"lx0.48"h And Rated At 45a Of Output
Current, The D12s1r845d Is Designed To Operate With An Input Voltage From 7v To 13.2v And Provide An
Output Voltage Adjustable From 0.6v To 3.3v. Each D12s1r845 Contains Two Power Trains Which Can
Provides Either An Interleaved Single Output, Or Two Independent Outputs. Multiple D12s1r845d Can Be
used in parallel to serve
Applications Where Output Currents Are In Excess Of 45a With Limitation Imposed Only By The Control
Circuit, Analog Or Digital. Designed For Superior Price/performance, The D12s1r845d Can Provide 3.3v
and 35A full load in ambient temperature up to 55 C with 200LFM airflow.
