LM3549: Recommend solution like LM3549 but use SPI

Hardy Xue

Part Number: LM3549
Other Parts Discussed in Thread: LP55281,

Hi Team,

Do we have RGB color sequential driver solution with SPI control and support buck boost to reduce LED headroom?

Like LM3549 but use SPI communication. Also, customer need to separate PWM control. So, LP55281 is not workable to customer.

If we have better solution, please let me know. Thank you.

Best regards,

Hardy

Hi Hardy,

We do not have such device both meet SPI communication and switch power supply.

Could we know which application does customer plan to use and which LED function do they want to achieve？
