EVALMA5342MS200WX2TOBO1

EVALMA5342MS200WX2TOBO1 is an evaluation board to evaluate two-channel, 200W/ch (8ohm at ±52.5V with heatsink) half-bridge class D audio power amplifier for Hi-Fi audio systems. This evaluation board demonstrates how to use MA5342MS 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). The reference design provides all the required housekeeping power supplies for ease of use. The two-channel design is scalable for power and the number of channels. Typical applications include AV receivers, home theatre systems, mini component stereos, powered speakers, sub-woofers, musical instrument amplifiers and car audio amplifiers.

• Output power: 200W x 2 channels (10 percent THD+N, 8ohm at ±52.5V)
• Over-current protection (OCP), high-side and low-side
• Over-voltage protection (OVP) and under-voltage protection (UVP), high-side and low-side
• DC protection(DCP) and over-temperature protection (OTP)
• PWM modulator: self-oscillating half-bridge topology with optional clock synchronization
