About "Vin standby current"

Why this parameter is eliminated in LM5175-Q1 datasheet?

(2)

IQ(VIN shutdown current) : MAX10 μA (VEN/UVLO = 0 V)

In this condition,how much voltage is at HDRV1 ?

Hi Kura,

1. The LM5175 was released latter than the after the LM5175-Q1. Due to customer request the standby current data was added to the datasheet for the LM5175. Standby current for both devices is the same.

2. When the device is in shutdown, the HDRV1 will be turned off. That means that the voltage from HDRV1 to SW1 will be 0V.

Thanks,

Garrett
