Technical Product Specification

Power Sub-system Intel® Server System SC5650HCBRP TPS

Revision 1.2

Intel order number E81443-002

All outputs are measured with reference to the return remote sense signal (ReturnS). The 3.3V

and 5V outputs are measured at the remote sense point; all other voltages are measured at the

output harness connectors.

4.2.2.5 DC / DC Converters Dynamic Loading

The output voltages remain within limits specified for step loading and capacitive loading as

specified in the following table. The load transient repetition rate is tested between 50 Hz and 5

kHz at duty cycles ranging from 10%-90%. The load transient repetition rate is only a test

specification. The Δ step load may occur anywhere between MIN load and MAX load conditions.
