Hi,

I need TI's confirm about the spec of LP55281.

I heard that there must be an internal engine to implement animation during the boot-up process. Please check LP55281 have it.

Also, please check if we can connect external power without using boost converter block.

thanks,

Hi TS,

Yes, you can disable the boost and use the external power. The default mode is disable.

Any more question please let me know, thanks!

Hi
There is no internal engine, if the engine is necessary, please check LP5569, LP5523.
Thanks!
