LM25119: PGOOD PIN

Part Number: LM25119

Hi

Could you please suggest, M25119 does not have a PGOOD pin.

How can I confirm that the IC is operating normally?

Is there any other PIN inside that can be detected?

If there is no similar function, please suggest how to do it with an external schematic?

    Hi Gareth,

    LM25119 doesn't have PGOOD pin and no other pins has similar function. You can compare output voltage (with divider) to an external reference voltage to determine if output voltage is in the desired range if necessary.
