48 Volt
48 VIN and 3.3 - 18 VOUT, Cool-Power ZVS Isolated DC-DC Converter Modules
Product Description
The Cool-Power ZVS Isolated Converter Module Series
consists of high density isolated DC-DC converters
implementing Zero Voltage Switching topology.
The 48 Vin Cool-Power series operates over a wide input
range of 36 V to 75 V with 3.3 V and 12 V output models and a
narrower range of 41 V to 57 V at 18 V output for PoE and
other applications. Both model sets produce 60W of output
power, yeilding an unprecedented power density of 400
W/in3.

These converter modules are surface mountable and only
~.5" square in area achieving ~50% space reduction versus
conventional solutions.
A switching frequency of 900 kHz allows for small input and
output ï¬lter 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 48 Volt PI31xx series 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.
