RECOM’s R-REF01-HB consists of a half-bridge suitable for voltages up to 1kV and a fully-isolated driver stage with isolated power supplies for the low-side and the high-side switching transistors. It is suitable for single gate drive supply voltages as low as +4V as well as dual gate drive supply voltages as high as +20V / -5V (30V max) with no maximum duty cycle limitations.

Features:

  • Optimized for very high switching speed
  • 2.5kV continuous input to output isolation
  • High gate-drive currents (up to 10A source and sink)
  • The RD is fitted with a SI8273 gate driver, but can be used with any pin-compatible gate driver with a PWM input (SI8274) or for gate driver ICs with reinforced isolation, for example the UCC21520 (dual pinout layout on PCB).
