The EPC9106 demonstration board is a reference design for a 150 W / 8 Ω Class D audio amplifier. The demonstration board uses a Bridge-Tied-Load (BTL) design, composed of four ground-referenced Half-Bridge Output Stages. This architecture and topology allows scalability and expandability.
The EPC9106 reference design has demonstrated 96% efficiency at 150 W / 8 Ω, and 92%efficiency at 250 W / 4 Ω.
The EPC9106 demonstration board features the EPC2016 enhancement mode (eGaN®) field effect transistor (FET), as well as the Texas Instruments LM5113 gate driver.
A complete block diagram of the circuit is given in Figure 1. For more information on the EPC2016 eGaN FET please refer to the datasheet available from EPC at www.epc-co.com. The datasheet should be read in conjunction with this quick start guide.
