Latest R-REF01-HB Reference Design Offers Isolated Power Supplies for Low and High Side Switching Transistors
Press Release Summary:
Richardson RFPD, Inc. has launched R-REF01-HB, a half-bridge gate drive power supply reference design with 2.5 kV continuous input-to-output isolation and high gate drive currents. It is configurable with various topologies such as LLC half-bridge, asymmetric duty cycle half-bridge, full-bridge and 3-phase B6 bridge. The product features 15 V to 42 V supply, shoot-through protection and TTL-compatible signal input. It is suitable for single-gate drive supply voltages and dual gate supply voltages, with no maximum duty cycle restrictions.
Original Press Release:
Richardson RFPD Introduces New Half-bridge Gate Drive Power Supply Reference Design from RECOM
Consists of a half-bridge suitable for voltages up to 1 kV and a fully-isolated driver stage with isolated power supplies
June 6, 2018 – Geneva, Ill.: Richardson RFPD, Inc. announced today the availability and full design support capabilities for a new reference design from RECOM Power, Inc. (RECOM).
The R-REF01-HB reference design 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 +4 V and dual-gate drive supply voltages as high as +20 V / -5 V (30 V max), with no maximum duty cycle limitations.
The new reference design is fitted with an Si8273 gate driver but can be used with any pincompatible gate driver with a PWM input or for gate driver ICs with reinforced isolation.
The R-REF01-HB can easily be configured for a variety of topologies, including LLC half-bridge, asymmetric duty cycle half-bridge (forward and flyback), active clamp half-bridge (forward and flyback), full-bridge, phase-shifted full-bridge, 3-phase B6 bridge, NPC B6 bridge (additional driving circuit for NPC required), double pulse test, synchronous boost converter, and synchronous buck converter.
Additional key features of the R-REF01-HB include:
• TTL-compatible signal input
• Single 15 V to 42 V supply
• Shoot-through protection
• Optimized for very high switching speed
• 2.5 kV continuous input-to-output isolation
• High gate drive currents (up to 10 A source and sink)
