Tool/software:

My application is to let the 10pcs LEDs flash 20ms every 2s. This requires a fast transform from shutdown into analog dimming mode.

Hi Xuesong,

Please double check if you need to use analog dimming mode / PWM dimming mode / flexible dimming mode.

Based on your description, it looks like PWM dimming mode / flexible dimming mode suits you. If you want a quick transition from shutdown into the specific dimming mode, then flexible dimming mode is more suitable. One method to get a quick transition from shutdown into flexible dimming mode is shown in this E2E FAQ - [FAQ] How to get a quick transition of TPS923655 / TPS923654 / TPS923653 / TPS923652 from shutdown into flexible dimming mode? - Power management forum - Power management - TI E2E support forums.

Best Regards,
