Part Number: LMR62421

Hi

My customer original use RT9293BGJ6 和ET5120A for LCM back light control but they meet LED flash issue.

so we promote LMR62421 EVM for them to test and without any issue.

But they need to controller the LED current to change the back light. so do you have an suggestion to add external circuit to meet this request?

BRs
