Why Choose IRS2092S Class D?
- IRS2092S Driver — Infineon’s self-oscillating MOSFET driver for ultra-low distortion Class D
- THD < 0.01% — Hi-Fi grade performance rivaling Class AB at a fraction of the heat
- >90% Efficiency — Minimal heatsinking required vs. Class AB equivalents
- 500W Output — Drives high-power subwoofers and PA speakers with authority
- Comprehensive Protection — OCP, OTP, and UVLO for reliable long-term operation
Typical Applications
- DIY subwoofer amplifier (home theater, car audio)
- High-power PA speaker amplification
- Bass channel in bi-amped speaker systems
- Studio monitor low-frequency amplification
- High-efficiency audio amplifier for embedded systems
Power Supply Requirements
Requires a dual-rail DC power supply (±25V to ±50V). For 500W output, use a toroidal transformer with ±45V / 6A+ rating. A ±35V supply delivers approximately 200W into 8Ω.
FAQ
Q: Does this board include a power supply?
A: No — a separate dual-rail DC power supply is required. The board accepts ±25V to ±50V DC.
Q: What’s the actual output power at ±35V into 8Ω?
A: Approximately 150–200W RMS. 500W is achievable at ±50V into 4Ω loads.
