13.4.2.7 DC/DC Converters Loading
The following table defines power and current ratings of three DC/DC converters located on the
PDB, each powered from +12V rail. The three converters meet both static and dynamic voltage
regulation requirements for the minimum and maximum loading conditions.

13.4.2.9 DC/DC Converters Voltage Regulation
The DC/DC converters’ output voltages stay within the following voltage limits when operating at
steady state and dynamic loading conditions. These limits include the peak-peak ripple/noise
specified in Table 132. The 3.3V and 5V outputs are measured at the remote sense point, all
other voltages measured at the output harness connectors.
