Proprietary isolated magnetic feedback 2 These converter modules are surface mountable and only Small footprint (0.57in ) enables PCB area savings ~0.5in square in area achieving ~50% space reduction versus Very low profile (0.265in) conventional solutions. Wide input voltage range operation (16 50V ) DC Output Voltage Device I Max On/Off Control, positive logic OUT Set Range Wide trim range +10/20% most models PI3108-00-HVMZ 3.3V 2.97 3.63V 10A Temperature Monitor (TM) & PI3109-00-HVMZ 5V 4 5.5V 10A Overtemperature Protection (OTP) PI3106-00-HVMZ 12V 9.6 13.2V 4.2A Input UVLO & OVLO and output OVP PI3111-00-HVMZ 15V 12 16.5V 3.33A Overcurrent protection with auto restart The switching frequency of 900kHz allows for small input and Adjustable soft start output filter components which further reduces the total size and 2250V input-to-output isolation cost of the overall system solution. The output voltage is sensed DC and fed back to the internal controller using a high performance isolated magnetic feedback scheme which allows for high Applications bandwidth and good common mode noise immunity. Wide Temperature, Aerospace & Defense Applications The PI31xx00HVMZ series requires no external feedback compensation and offers a total solution with a minimum number Space-Constrained Systems of external components. A rich feature set is offered, including output voltage trim capability, output overvoltage protection, Isolated Board-Level Power adjustable soft start, overcurrent protection with auto restart, over and under input voltage lockout and a temperature monitoring and Package Information protection function that provides an analog voltage proportional to the die temperature as well as shut down and alarm capabilities.
