EVALAUDAMP25TOBO1

EVAL_AUDAMP25 MA5332 evaluation board is a two-channel, 200 W/ch (4 Ω at ±36.5 V; with heatsink) half-bridge class D audio power amplifier for Hi-Fi audio systems. This evaluation board demonstrates how to use MA5332 IC, implement protection circuits, and design an optimum PCB layout using Infineon integrated Class D IC. This reference design does not require additional heatsink or fan cooling for normal operation (one-eighth of continuous rated power).

• Output power: 200W x 2 channels (10 percent THD+N, 4 ohm at ±36.5V)
• Multiple protection features: OCP, OVP, UVP, OTP, DC protection
• PWM modulator: self-oscillating half-bridge topology with optional clock synchronization
