Hi 

My customer likes to understand the difference between PS_HOLD vs EN_PWR_On pin.

When 7.5V is applied to the Vin and En Pwr_on, Does the En Pwr_on need to be always set to high to provide those supply Vout?

In such condition, does PS_HOLD signal is compulsory to hold the LP8725in order to remain in on state?

Rgds,
Kelvin

    Hi Kelvin,

    I assume based on your question, this would assume CONFIG=1.

    In this set up, PWR_ON starts the power on sequence. PS_HOLD is the power supply hold input and used to initiate the shutdown sequence.

    Thanks,
    Field
