REFMA5332BTLSPSTOBO1: 200W x1 @ 4 Ω, 35 ~ 80V in

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:
