12V High-Efficiency Class D Audio Reference Designs

These reference designs are intended to operate with or independent of the GaN Systems reference design bundle kit GS-EVB-AUD-BUNDLE1-GS to accommodate a Single-Rail Power Supply configuration. This reference design, GS-EVB-AUD-AMP12V-GS supports both a ‘direct’ +12V to +18V Single-Rail Power Supply, and a ‘boosted’ +12V to +18V Single-Rail Power Supply configuration. The Amplifiers are designed to allow the scaling for both power supply considerations. A companion boost converter is also provided.


  • Single-Phase and Dual-Phase 12V Boost Converter Designs
  • Two versions of a Boost Converter are provided to allow for the best cost versus power output trade-off: 1) Single-Phase Boost Converter and 2) Dual-Phase Boost Converter
  • Direct +12V to +18V VIN Supply to +/- 32V VOUT Boost Converter
