Both model sets Proprietary isolated magnetic feedback produce 60W of output power, yeilding an unprecedented power 2 3 Small footprint (0.57in ) enables PCB area savings density of 400W/in . Very low profile (0.265in) Output Voltage On/Off Control, positive logic Device I Max OUT Set Range Wide trim range +10/20% for PI3105-00-HVIZ (+10/10% for other models) 3.3V 2.97 3.63V 18A PI3101-00-HVIZ 12V 9.6 13.2V 5A Temperature Monitor (TM) & PI3105-00-HVIZ Overtemperature Protection (OTP) 18V 16.2 19.8V 3.3A PI3110-01-HVIZ Input UVLO & OVLO and output OVP These converter modules are surface mountable and only Overcurrent protection with auto restart ~0.5in square in area achieving ~50% space reduction versus Adjustable soft start conventional solutions. 2250V input-to-output isolation DC A 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 Applications back to the internal controller using a proprietary isolated magnetic feedback scheme which allows for high bandwidth and good Space-Constrained Systems common mode noise immunity. Isolated Board-Level Power The 48 Volt PI31xx series requires no external feedback Network Power Systems compensation and offers a total solution with a minimum number of external components. A rich feature set is offered, including Telecommunications output voltage trim capability, output overvoltage protection, Distributed Power Architecture adjustable soft start, overcurrent protection with auto restart, over and under input voltage lockout and a temperature monitoring and PoE Power Over Ethernet protection function that provides an analog voltage proportional to IPoL Isolated Point-of-Load Power the die temperature as shut down and alarm capabilities.
