IRCore1000M ±70V 2Ω Mono Class-D Amplifier Module IRFB4227
A 2Ω capable class-d amplifier designed for driving high powered subwoofers and PA full range speakers.
FZT853/FZT953 high power gate buffers were used for driving IRFB4227 output mosfets with ease.
Only split ±70V supply is required (LLC SMPS recommended), no need for aux supplies.
