Infineon Technologies IRAUDAMP19 Reference Design Board
Infineon Technologies IRAUDAMP19 Reference Design Board is a two-channel 100W/channel half-bridge class D audio amplifier with a single power supply. This design board demonstrates the usage of the IR4301 IC with a single power supply, implements protection circuits, and helps create an optimized PCB layout. Protections include overcurrent (OCP), high- and low-side overvoltage (OVP), high- and low-side overtemperature (OTP), and undervoltage (UVP). Infineon Technologies IRAUDAMP19 Reference Design Board requires no additional heatsink or fan cooling for normal operation. Typical applications include AV receivers, home theater systems, mini-component stereos, powered speakers, subwoofers, and musical instrument amplifiers.
