Full bridge driver for IGBT, GaN and SiC devices

Infineon Technologies has launched a full bridge transformer driver for power supply designs using IGBT, SiC or GaN devices.

The EiceDRIVER Power 2EP1xxR family of full-bridge transformer drivers provides isolated gate drive power for the different technologies, simplifying the options for power supply designers.

The devices provide asymmetrical output voltages to supply isolated gate drivers in a cost-effective and space-saving manner. This makes the 2EP1xxR particularly suitable for industrial or consumer applications requiring isolated gate drivers, including solar applications, electric vehicle charging, energy storage systems, welding, uninterruptible power supplies and drive applications.

• 125 V high-side gate driver protects battery equipment
• Gate driver adds reinforced isolation
• 1200 V half-bridge driver family with active Miller clamp

The 2EP1xxR family comes in a compact TSSOP8 pin package with power integration and optimizations to generate an asymmetric output voltage using the proprietary duty-cycle adjustment capability. The devices support a wide input voltage range up to 20 V as well as integrated temperature, short-circuit and undervoltage lockout (UVLO) protection to prevent unwanted system faults.

The 2EP1xxR family is available in the four variants. The 2EP100R and 2EP101R are optimized for low component count designs for IGBT and SiC MOSFET gate driver power supplies while the the 2EP110R allows fine adjustment of the duty-cycle to match the output voltage ratio to the application requirements of SiC and GaN power switches.

The 2EP130R is optimized for highly flexible designs to meet different application requirements with 5-stage overcurrent protection, 41 selectable switching frequencies or synchronization with external PWM for transformer matching, and 41 selectable duty-cycle options to adjust the output voltage.

Evaluation boards EVAL-2EP130R-VD, EVAL-2EP130R-PR and EVAL-2EP130R-PR-SIC are available to support customer evaluation. Further information is available here.

All four variants of the EiceDRIVER Power 2EP1xxR are now available.
