EPC2106 GaN power transistor offers power systems designers a solution that switches over 2 MHz resulting in no interference with the AM band, reducing costs for filtering, thus making it ideal for low distortion Class-D audio.
EL SEGUNDO, Calif. — August 2015 — EPC announces the EPC2106, an enhancement-mode monolithic GaN transistor half bridge. By integrating two eGaN® power FETs into a single device, interconnect inductances and the interstitial space needed on the PCB are eliminated. This increases both efficiency (especially at higher frequencies) and power density, while reducing assembly costs to the end user’s power conversion system.
The EPC2106 half-bridge component has a voltage rating of 100 V with a typical RDS(on) of 55 mΩ, output capacitance less than 600 pF, zero reverse recovery (QRR), and a maximum pulsed drain current of 18 A. The low on-resistance and capacitance of GaN enables high efficiency and significantly reduces distortion in Class-D systems. The EPC2106 comes in an extremely small 1.35 mm x 1.35 mm chip-scale package for improved switching speed and thermal performance for increased power density.

The low on-resistance and capacitance of GaN enables high efficiency and significantly reduces distortion in Class-D systems. To demonstrate, the EPC9106 Class-D audio amplifier reference design uses high frequency switching gallium nitride power transistors in the power stage providing precise high-power reproduction of the Class-D audio signal. The system demonstrates high efficiency, size reduction and eliminates the need for a heat sink while delivering prosumer quality sound.
