GaN Technology Powers New Class-D Audio Amplifier in Efficient Power Conversion's Latest Reference Design
Unleash Powerful Audio with EPC's GaN Technology: Introducing the EPC9192 Reference Design
BonChip Electronics, a leading distributor of innovative power electronics solutions, is excited to announce the availability of EPC's groundbreaking EPC9192 reference design. This innovative platform empowers audio amplifier designers to create powerful, compact, and highly efficient Class-D amplifiers, unlocking the full potential of Gallium Nitride (GaN) technology.
Unveiling the Power of eGaN FETs
The EPC9192 showcases the exceptional capabilities of EPC's advanced 200V eGaN FETs (EPC2307). Utilizing a ground-referenced, split dual supply Single-Ended (SE) design, the EPC9192 delivers an impressive 700 watts per channel into a 4Ω load, setting a new standard for performance and efficiency in the audio amplifier landscape.
Modular Design for Scalability and Customization
The EPC9192 boasts a unique modular design, offering unparalleled flexibility for developers. The motherboard houses two Pulse Width Modulation (PWM) modulators and two half-bridge power stage daughterboards, forming a complete two-channel amplifier with housekeeping supplies and essential protections. This modularity empowers users to customize the PWM modulator and power stage sections, facilitating the evaluation and comparison of different devices and modulation techniques.
Key Features and Benefits
- Exceptional Power Density: Delivers a remarkable 700W Class-D power stage in a compact size of only 4 cubic inches, including the output filter and heatsink.
- Simplified Power Supply: Requires a single, regulated 12V power supply input for housekeeping functions.
- Versatile Power Stage: Accommodates a dual split supply input, unregulated, ranging from ±42V to ±85V for the power stage, offering a wide range of operating configurations.
- Comprehensive Input Options: Supports both balanced (XLR) and unbalanced (RCA) analog inputs, catering to diverse audio source connections.
- Configurable Modes: Offers the flexibility to operate in two independent SE channels or a single-channel BTL mode, adapting to various speaker configurations.
- Robust Protection Suite: Features comprehensive under-voltage, over-voltage, over-current, and over-temperature protections, ensuring safe and reliable operation.
- High-Frequency Switching: Employs a switching frequency exceeding 600 kHz, minimizing audible noise and enabling a more compact design.
Unmatched Performance
The EPC9192 delivers exceptional performance metrics, making it a perfect choice for demanding audio applications:
- High Power Output: Delivers 700 W at 2 ohms to 4 ohms, and 350 W at 8 ohms per channel.
- Bridge-Tied Load (BTL) Capability: Can be configured for BTL mode, reaching an impressive 1400 W at 4 ohms to 8 ohms.
- Low Distortion: Maintains incredibly low Total Harmonic Distortion plus Noise (THD+N) of less than 0.005%, guaranteeing pristine audio reproduction.
- High Signal-to-Noise Ratio: Boasts a remarkable Signal-to-Noise Ratio (SNR) exceeding 120 dB, ensuring a clean and transparent listening experience.
- Ultra-Low Noise Floor: Offers a minimal noise floor of only 40 µV, minimizing unwanted background noise.
- Wide Frequency Response: Provides a flat frequency response from 5 Hz to 20 kHz with a tolerance of ±0.5 dB, regardless of the load, ensuring faithful audio reproduction across the entire audible spectrum.
Alex Lidow, CEO of EPC, emphasizes the significance of the EPC9192: "The EPC9192 is a powerful tool for audio amplifier designers looking to leverage the benefits of GaN technology. With high-power density and scalability, it enables rapid prototyping of compact, high-performance Class-D amplifiers."
