Infineon Technologies REF_MA5332BTLSPS Reference Board

Infineon Technologies REF_MA5332BTLSPS 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. The MA5332M is a BTL channel, 200W/ch (4Ω at 40V) class D audio power amplifier for home audio systems.

The Infineon REF_MA5332BTLSPS Reference Board does not require additional heatsink or fan cooling for normal operation (one-eighth of continuous rated power). The REF_MA5332BTLSPS includes all the necessary housekeeping power supplies allowing ease of use.

Features

  • Output power:
    • 200W x 1 channels (10 percent THD+N, 4Ω at 40V)
  • Pulse width modulator (PWM):
    • Self-oscillating half-bridge topology with optional clock synchronization
  • Multiple protection features:
    • Overcurrent protection (OCP), high-side and low-side
    • Overtemperature protection (OTP)

Applications

  • Smart speakers
  • Sound bars
  • Sub-woofers
  • Powered speakers
  • Musical instrument amplifiers
  • Car audio amplifiers
