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 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 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.
