Description
The Cool-Power
TM PI3101 is a very high density
isolated DC-DC converter implementing a high
efficiency soft-switching power architecture. The
PI3101 operates over a wide range input of 36V to
75Vdc, delivering ~60W of output power (3.3Vout @
18A), yielding an unprecedented power density of
400W/in
3. The PI3101 is available in a space saving
surface mountable 0.87” x 0.65” x 0.265” package,
achieving
~50%
space
reduction
versus
conventional solutions.
The switching frequency of 900kHz allows for small
input and output filter components which further
reduces the total size and cost of the overall system
solution. The output voltage is sensed and fed back
to the internal controller using a proprietary isolated
magnetic feedback scheme which allows for high
bandwidth and good common mode noise immunity.
The
PI3101
requires
no
external
feedback
compensation and offers a total solution with a
minimum number of external components. A rich
feature set is offered, including output voltage trim
capability, output over-voltage protection, adjustable
soft-start, over-current protection with auto-restart,
over and under input voltage lockout and a
temperature monitoring and protection function that
provides an analog voltage proportional to the die
temperature as shut down and alarm capabilities.
