LM5161: Fly Buck Converter with very low Iq.

Part Number: LM5161

Hello E2E Experts,

Good day.

Similar to LM5161 but something with 500uA or less would be ideal since I have a battery-powered device.

Thank you in advance for your support.



  • Hello

    For a fly-buck converter you would need a device that features a FPWM mode.

    In that case the light load Iq will always be greater than an ordinary buck operating in light load mode.

    You might wish to look at the LM5168F or LM5169F.  However, I don't think you will get very low Iq with a FPWM fly-buck
