TPS92210: 0-10V dimming ratio

Part Number: TPS92210
Other Parts Discussed in Thread: PMP6023

Hi,

I noted that the 0-10V dimming ratio is 9:1. what does this mean?

are there many methods of 0-10V dimming or is it always an isolated interface using an opto-coupler to transfer the signal to control the reference voltage?

is the 0-10V dimming circuitry integrated in our 0-10V dimming devices or always external system level circuitry?

Thanks,

Kevin

Hello,

I am not sure what you mean by the 9 to 1 dimming range. I could not find any information in regards to that. Could you let me know what document this references?

However, I found an application note that discusses how to do LED dimming with the TPS92210 that you might find helpful at the following link.

Hi Mike,

Thanks for the reference guide, it is definitely interesting and helpful to better understand the device.

I read that in PMP6023 reference design guide's introduction.

is 0-10V dimming only used in isolated designs?

Thanks,

Kevin

Hello Kevin,

I believe that you could still use this technique if it was not isolated. However, for safety it is probably the most popular.
