kHz at duty cycles ranging from 10%-90%. The load transient repetition rate is only a test
specification. The step load may occur anywhere between the MIN load and MAX load
conditions.

2.4.3.1 DC/DC Converter Capacitive Loading
All outputs of the DC/DC converter are stable and meet all requirements with the following
capacitive loading ranges.
+3.3VDC
+5VDC
-12VDC
Note: Refer to the Power Supply specification for the equivalent data on +12V and +5VSB output.
2.4.3.2 DC/DC Converters Closed Loop Stability
Each DC/DC converter is unconditionally stable under all line/load/transient load conditions,
including capacitive load ranges. A minimum of 45 degrees phase margin and –10dB-gain
margin is required.
2.4.3.3 Common Mode Noise
The common mode noise on any output does not exceed 350 mV peak-peak over the frequency
band of 10 Hz to 30 MHz.
