TPS61196: Is there a way to setup the current for each channel?

David Huang

Part Number: TPS61196

My customer is asking for a solution to drive LED with the maximum current in each channel can be setup separately(e.g. an Iset for each channel).

The TPS61196's spec(they want 3-5 channels) looks like a good fit to the customer's design but I don't think it can set the current separately as I read the datasheet.

Do we have a device similar to TPS61196 that can setup the current for each channel?

Thanks

Hi David,

TPS61196 has six channels with corresponding separated PWM input. The maximum current is set by ISET for all six channels, but you can apply different duty cycle to each channel to get different output current.

Hi Robin

Do we have a solution with Iset for each channel?

Hi David,

We have no such device now.
