TPS61169: TPS61169 CTRL pin sink current

Part Number: TPS61169

Dear Sir/Madam,


My customer wants to connect one MCU output port to two TPS61169 CTRL pin to control two TPS61169 at the same time. Please refer to the attached file.

As far as I know, this relates to CTRL pin sink current and MCU port source current. Right? So I looked TPS61169 datasheet, but couldn’t find it.

Would you please check how much current MCU output port need to control PWM diming for two TPS61169 ?

If there is anything else to consider, please let me know.
