WE-GDT Isolated Gate Drive Transformer

WE-GDT Isolated Gate Drive Transformer

To control secondary-side MOSFETs, synchronously-rectified flyback converters require electrically-isolated gate drive transformers. The construction of Wurth Electronics' WE-GDTI series in an EP7 package offers basic insulation for operating voltage of 250 VRMS compliant with EN 61558-2-16. It allows a test voltage of 2500 VDC between the primary and secondary windings. The μVs product in this series is 70% higher than that in the previous WE-GDT series. The EP7 core acts as a screen against external magnetic fields, at the same time reducing its own magnetic field. These transformers are supplied with three windings and with up to five different winding ratios.

Characteristic
  • Excellent performances in small package (EP5)
  • 1 or 2 secondary windings
  • 4 different turns ratios
  • 1500 VDC insulation test voltage
Applications
  • Suitable for signal and power application
  • Designed for high-efficiency SMPS gate drive application
  • Synchronous flyback
