Where is the Class-D amplifier example for B-G474E-DPOW1?

[GregKN]

Hello,

i read the UM2577 pdf, the user manual for the Discovery kit with STM32G474RE MCU (B-G474E-DPOW1 board). On page 29, chapter 13.3, an audio class-D amplifier example with separate application note is mentioned. Where can i find this app note and/or the example?

Kind regards,

Greg

Perhaps it is also confidential, like the source code of AN5142?

Personally, it would be interesting to get further information about H-bridge PWM programming with STM32 HRTIM for Class-D amp application.

But i understand that ST also wants to sell their Class-D Amplifier IC... ;)

Are there any other app notes, manuals etc. covering PWM H-bridge (class-D) programming with MCUs, preferably from ST, anyone can recommend? Thanks in advance.

Hi @GregKN​ ,

I think that AN5142 (Class-D audio amplifier implementation on STM32 32-bit Arm® Cortex® MCUs). Right?
