EPC91109 180 W GaN Buck Converter Evaluation Board

The EPC91109 evaluation board from EPC is ideal for USB PD 3.1, laptops, battery-powered equipment, and portable electronics up to 180 W

Image of EPC EPC91109 180 W GaN Buck Converter Evaluation BoardThe EPC91109 from EPC is a compact and efficient two-phase synchronous buck converter evaluation board. It is optimized for step-down conversion from 20 V to 36 V input to 12 V, 16 V, or 20 V output, making it ideal for USB Power Delivery (USB PD 3.1), laptops, battery-powered equipment, and portable electronics up to 180 W.

At the heart of the EPC91109 are four EPC2057 50 V eGaN® FETs, driven by the Analog Devices LTC7890 dual-phase controller. With a compact 24 mm × 24 mm power stage footprint and no need for a heatsink or forced-air cooling, this board demonstrates the performance and thermal advantages of GaN over silicon in high-density designs.

Features
  • High-efficiency step-down conversion: 20 V to 36 V input to 12 V/16 V/20 V output
  • Supports up to 14.3 A output current (180 W max)
  • Two-phase interleaved or dual-output buck configurations
  • Ultra-compact power stage: only 24 mm × 24 mm
  • >98% peak efficiency at full load with no heatsink or airflow
  • Built-in jumpers for mode, voltage, and dead-time selection
  • Configurable light-load operation: Burst, skip, or CCM
Applications
  • USB PD 3.1 up to 180 W
  • Laptop and portable PC power systems
  • Battery-powered medical or industrial devices
  • Drones and robotics
  • Fast-charging adapters and mobile power supplies
