PI3106-01-HVIZ
Cool-Power^® Series
18-36V Input, 12V / 4.2A / 50W Output
Very High Density Isolated DC-DC Converter (334W/in³)
Description
The Cool-Power^® PI3106-01-HVIZ is a very high
density isolated DC-DC converter implementing a
high efficiency soft-switching power architecture.
The PI3106-01-HVIZ operates over an input range
of 18V to 36Vdc, delivering ~50W of output power
(12Vout @ 4.2A), yielding an unprecedented power
density of 334W/in³. The PI3106-01-HVIZ 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 PI3106-01-HVIZ 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.
