Award winning EPC9005 development board facilitates rapid design of high frequency switching power conversion systems based on the 40 V EPC2014 eGaN FET

EL SEGUNDO, Calif. – November 2013 - Efficient Power Conversion Corporation (www.epc-co.com; www.epc-co.com.cn) announces that its EPC9005 development board has been recognized with two industry awards in China; namely, Optimized Development Award of the Top 10 Power Products Award 2013 presented by Electronics Product China and Leading Product Award of China Innovation Award 2013 presented by EDN China magazine.

EPC9106 Class D audio amplifier reference design, using high frequency switching gallium nitride power transistors, demonstrates efficiency enhancement, size reduction and eliminates need for a heat sink while delivering prosumer quality sound.

EL SEGUNDO, Calif. — November 2013 — Efficient Power Conversion Corporation (EPC) introduces the EPC9106, a reference design for a 150 W, 8 Ω Class D audio amplifier. This demonstration board uses a Bridge-Tied-Load (BTL) design, composed of four ground-referenced half-bridge output stages, which allows scalability and expandability of the design. All elements that can impact the sonic performance of Class D Audio systems are minimized or eliminated in an eGaN FET-based system.

Power conversion at switching frequencies of 10 MHz and above requires both high-speed transistors and high frequency capable packaging. eGaN FETs have demonstrated their ability to improve high frequency power conversion compared with the aging power MOSFET by providing unmatched device performance as well as packaging.
