The PI3106-01-HVIZ operates over an input range of 18V to 36Vdc, delivering ~50W of output power (12Vout @ 4.2A), yielding an unprecedented power density of 334W/in 3. The PI3106-01-HVIZ is available in a space saving surface mountable 0.87” x 0.65” x 0.265” package, achieving ~50% space reduction versus conventional solutions. 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 PI3106-01-HVIZ 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. PI3106-01-HVIZ 18V-36Vin, 12Vout, 4.2A Very High Density Isolated DC-DC Converter Features 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 in 2) enables PCB area savings Very low profile (0.26 in) Industrial input voltage range (18-36Vdc) 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 Adjustable soft-start Starts up into high capacitive loads 2250V input to output isolation Applications Industrial DC-DC power conversion Package Information Surface Mountable 0.87” x 0.65” x 0.265” package Typical Application Schematic Diagram Figure 1 Picor PI3106-01-HVIZ Shown With System Fuse, Filter, Decoupling And Extended Soft Start PI3106-01-HVIZ |
