28VIN, 3.3 to 15VOUT, ZVS Isolated Converter Module Family
Product Description
Features & Benefits
• Efficiency up to 88%
The ZVS Isolated Converter Module Series consists of high
density isolated DC-DC converters implementing Zero Voltage
Switching topology.
• High switching frequency minimizes input filter
requirements and reduces output capacitance
The 28VIN series operates over a wide range input of 16V
to 50VDC, delivering 50W of output power, yielding an
unprecedented power density of 334W/in3.
• Proprietary “Double-Clamped” ZVS Buck-Boost Topology
• Proprietary isolated magnetic feedback
• Small footprint (0.57in2) enables PCB area savings
• Very low profile (0.265in)
These converter modules are surface mountable and only
~.5” square in area achieving ~50% space reduction versus
conventional solutions.
• Wide input voltage range operation (16 – 50VDC
)

• Input UVLO & OVLO and output OVP
• Overcurrent protection with auto restart
• Adjustable soft-start
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 high performance
isolated magnetic feedback scheme which allows for high
bandwidth and good common mode noise immunity.
• 2250VDC input to output isolation
Applications
• Wide Temperature, Aerospace & Defense Applications
• Space Constrained Systems
The PI31xx-00-HVMZ 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 well as shut down
and alarm capabilities.
• Isolated Board Level Power
Package Information
• Surface Mountable 0.87” x 0.65” x 0.265” package
• Weight = 7.8 grams
