The REF_MA5332BTLSPS reference board is a one BTL channel, 200 W/ch (4 Ω at 40 V) class D audio power amplifier for home audio systems. This reference board demonstrates how to use MA5332M IC with a single power supply 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). The reference design provides all the required housekeeping power supplies for ease of use.
Features:
Output power:
200 W x 1 channels (10 percent THD+N, 4 Ω at 40 V)
Multiple protection features:
Over-Current Protection (OCP), high-side and low-side
Over-Temperature Protection (OTP)
PWM modulator:
Self-oscillating half-bridge topology with optional clock synchronization
Benefits:
Single power supply
Full-bridge output
High audio quality
Low noise
High efficiency
