Reference design/Evaluation board - 200 W / 4 Ohms x 2-channel class D audio power amplifier featuring MA5332
The EVAL_AUDAMP25 MA5332 evaluation board is a 2-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).
Summary of Features
Output power:
200 W x 2 channels (10 percent THD+N, 4 Ω at ±36.5 V)
Multiple protection features:
Over-Current protection (OCP), high-side and low-side
Over-Voltage protection (OVP)
Under-Voltage protection (UVP), high-side and low-side
DC Protection(DCP)
Over-Temperature protection (OTP)
PWM modulator:
Self-oscillating half-bridge topology with optional clock synchronization
Benefits
Split power supply
SE/BTL/PSE output
High audio quality
Low noise
High efficiency
