TPS2420: Minimum Load

Part Number: TPS2420
Other Parts Discussed in Thread: TPS2595

Hi Team,

I have a customer using the TPS2420 and want to verify the following:

Is there any minimum load requirements for the TPS2420 to work? In other words, does the device require any minimum current flowing through its internal MOSFET to the load for it to detect hot plug event and enable the voltage for load?

I see the datasheet indicates an enable pin but want to confirm and check if a minimum is required.

Thanks for the help in advance,

Jerry

  • Hi Jerry,

    There is no constraint on the minimum load. As soon as the enable pin is made active, the device starts and brings up the output voltage, even without any load.

    Can you share the system requirements. Please look at TPS2595, new device with better performance and let me know if you have any questions.

    Best Regards,
    Rakesh
