The PFE1100-12-054NA AC-DC power supply is a
fully DSP controlled, highly ef?cient front-end. It
incorporates resonance-soft-switching technology
and interleaved power trains to reduce component
stresses, providing increased system reliability and
very high ef?ciency. With a wide input operating
voltage range and minimal linear derating of
output power with input voltage and temperature,
the PFE1100-12-054NA maximizes power availabil-
ity in demanding server, switch, and router appli-
cations while keeping power dissipation to a
minimum.
The front-end is fan cooled and ideally suited for
server integration with a matching air?ow path.

The fan control proved to be very effective at
adjusting the speed of the fan as the output current
demand increases or decreases, keeping ambient
noise to a minimum and helping ensure power is
not wasted through inef?cient fan control.
Cooling is managed by a fan controlled by the DSP
controller. The fan speed is adjusted automatically
depending on the actual power demand and sup-
ply temperature and can be overridden through the
I 2 C bus.
The PFC stage is digitally controlled using a state-
of-the-art digital signal processing algorithm to
guarantee best ef?ciency and unity power factor
over a wide operating range.
The DC-DC stage uses soft switching resonant
techniques in conjunction with synchronous front-
ends. An active ORing device on the output en-
sures no reverse load current and renders the sup-
ply ideally suited for operation in redundant
power systems.
The Always On standby output with selectable
voltage level (3.3/5V) provides power to external
power distribution and management controllers.
Selection is straightforward and is set by a pin on
the output connector. Its protection with an active
ORing device provides for maximum reliability.
Status information is provided with front-panel
LEDs. In addition, the power supply can be
controlled via the I 2 C bus and programmed for
output voltage, current limitation, and fan speed.
In addition, it allows full monitoring of the supply,
including input and output voltage, current,
power, and inside temperatures.
