Extended ferrites improve cooling of low-profile resonant transformers
PAYTON AMERICA 200Watt (55mm x 40mm x 8mm) transformer is designed for a resonant half bridge operation. Firm can design the low profile transformers for many switch mode topologies with operating frequencies of over 200khz. Device provides input voltage is 400V with over 3000Vrms isolation and full 8mm creepage and clearance. The total power losses are under 3.8 watts with 40C temperature rise with no additional cooling. The efficiency of this magnetic is in the 98% range. The parts can be used without a heatsink.
