PI3106-00-HVMZ
Cool-Power® Series
16-50V Input, 12V / 4.2A / 50W Output
Very High Density Isolated DC-DC Converter (334W/in3)
Description
The Cool-Power® PI3106-00-HVMZ is a very high
Features
density isolated DC-DC converter implementing a
high efficiency soft-switching power architecture.
The PI3106-00-HVMZ operates over an input range
of 16V to 50Vdc, delivering ~50W of output power
(12Vout @ 4.2A), yielding an unprecedented power
density of 334W/in3. The PI3106-00-HVMZ is
available in a space saving surface mountable 0.87”
x 0.65” x 0.265” package, achieving ~50% space
reduction versus conventional solutions.
Efficiency up to 88.5%
High switching frequency minimizes input filter
requirements and reduces output capacitance
Proprietary “Double-Clamped” ZVS Buck-Boost
Topology
Proprietary isolated magnetic feedback
Small footprint (0.57 in2) enables PCB area
savings
Very low profile (0.26 in)
MIL-COTS input voltage range operation (16-
50Vdc)
On/Off Control, positive logic
+10/-20% Trim
Temperature Monitor (TM) & Over-Temperature
Protection (OTP)
Input UVLO & OVLO and output OVP
Over current protection with auto restart
Starts up into high capacitive load
Adjustable soft-start
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 PI3106-00-HVMZ 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.
