EPC Introduces Two eGaN ICs Combining Gate Drivers with High Frequency GaN FETs for Improved Efficiency, Reduced Size and Lower Cost

EPC EPC2112 EPC2115

EPC2112 and EPC2115 GaN-based monolithic integrated solutions offer power systems designers the ability to increase efficiency in an extremely small size.

Efficient Power Conversion Corporation (EPC) announces the EPC2112 and EPC2115 enhancement-mode monolithic GaN power transistor with integrated driver products. The EPC2112 is a 200 V, 40-mΩ eGaN® FET plus integrated gate driver. In comparison, the EPC2115 is an integrated circuit with dual 150 V, 70-mΩ eGaN FETs plus gate drivers. Both products are capable of operating up to 7 MHz and are available in low inductance, extremely small, 2.9 mm × 1.1 mm BGA surface-mount passivated die.

These monolithic ICs enable designers to improve efficiency, save space, and lower costs compared to silicon-based solutions. The ultra-low capacitance and zero reverse recovery of eGaN FETs enable efficient operation in many topologies.

In both products, the integrated driver is specifically matched to the eGaN device to yield optimal performance under various operating conditions. Performance is further enhanced due to the small, low inductance footprint. Monolithic integration eliminates interconnect inductances for higher efficiency at high frequency. This is especially important for high frequency applications such as resonant wireless power, and high frequency DC-DC conversion.

As design examples for these new ICs, two differential class-E amplifier development boards are available for order. The EPC9089 is an AirFuel™ Alliance compatible class 4 (33 W) and uses the EPC2112. Whereas, the EPC9088 is a class 3 (16 W) amplifier using the EPC2115. The EPC2112 is also featured in a new demonstration board, the EPC9131, for a 300 kHz SEPIC converter low voltage DC-DC application.
