Infineon Technologies IRS2461S | Demoboard REF_IRS2461S_5KW
2.5kW x 2 channel Class D audio amplifier using IRS2461S
Details
| Topologie | Class D Audio Amplifier |
| IC-Revision | 1.0 |
Beschreibung
The REF_IRS2461S_5KW evaluation board is a two-channel, 2500W/ch (2Ω at ±103.5V) half-bridge Class D audio power amplifier for after market car audio or high-power audio system applications. This evaluation board demonstrates how to use the IRS2461S controller IC, implement protection circuits, and design an optimum PCB layout. This design can be scaled for a 1600W/ch (4Ω at ±120V) and instruction of doing so are included.
Eigenschaften
- Output power: 2500W x 2 channel (1% THD+N)
- Multiple protection features
- Over-current protection (OCP), high side and low side FETs
- Over-voltage protection (OVP)
- Under-voltage protection (UVP)
- Over-temperature protection (OTP)
- PWM modulator
- Self-oscillating half bridge topology with optional clock synchronization
Typische Anwendungen
- Class D amplifier
