Part Number: LP5810

Tool/software:

Hi , 

I wanted to use an I2C based PWM generator .   Can I use LP5810DDSDR  as shown below ? I need this PWM to drive TPS922054DRRR  , only when when a STROBE is active  . Please share your suggestions .

Also Any I2C based I/O expander (preferably 4 channel) with one pin can serve PWM ?

    Hi Nikhlraj,

    Yes, LP5810 can be used to provide PWM voltage output with an external pull up resistor as the diagram shown.

    Besides that as LP5810 output is constant current control, so the resistor R6 is not needed.

    I think the LP5810 is the best recommendation.

    Best regards,

    Felix
