TPSM33620-Q1: Input operating quiescent current (non-switching) question

Part Number: TPSM33620-Q1

Tool/software:

Hi Team,

As datasheet said, Input operating quiescent current (non-switching)  at TA = 25°C, VEN = 3.3V, VFB = 1.5V is typical 1.2uA.

How can we let VFB = 1.5V?

Regards,

Roy

    Hi Roy,

    The input operating non-switching quiescent current is the current used by the device's internal circuitry when not accounting for switching losses.

    The device is not operational in this state as the feedback pin is held externally high to stop the device from switching.

    Thank you,
