TPS61166: TPS61166、TPS61500Chip application problem

Part Number: TPS61166
Other Parts Discussed in Thread: TPS61500

Tool/software:

We use it in endoscope headend lighting, which is related to CMOS exposure and has 30HZ application scenarios.

1. Regarding the drive current range and PWM frequency limitation of TPS61166, the actual requirement is to use around 30HZ frequency. If the PWM control signal frequency is 30HZ, can the chip be used normally? If yes, what is the difference with the reference design? If not, what problems will arise?

2. Regarding TPS61500, there are two questions. The first is whether it can support PWM from 30-5kHz. The second is whether it is necessary to use Analog PWM. Are there any other ways? Please provide relevant information.

Our requirements are quite special. Could you please help us find a compatible 30Hz switching LED driver solution?

I have seen E2E posts from a long time ago and wonder what the situation is now?
