LM5176: EN Current

Part Number: LM5176

Hi E2E,

Our customer want to save IQ so increase the RUV1 and RUV2.

How much resistance should be added? could we use 2.49M or more to design it?

    Julian,

    Thanks for reaching out with your questions.

    IT is possible to implement the resistor divider with high resistor values. Please be aware that using high resistance values will reduce the impact of noise on the signal. The other thing that should be taken into account is the start-up voltage and shutdown voltage the is set by the UVLO hysteresis current.

    Please let me know if you have any questions.

    Thanks,

    Garrett
