Other Parts Discussed in Thread: TUSB7320, TPS74401

Hello,

My customer selects a voltage regulater for TUSB7320.

Is it possible to use 200mA for 3.3V, 800mA for 1.1V?

There is no maximum current consumption value.

How should I design a power supply with margin?

Regards

Hello Aoyama-san,

The reference design uses two TPS74401 in order to generate the 3.3V and 1.1V. This device provides you a wide power range and high voltage stability.

Best regards,

Diego.

Hi Diego,

Thank you for your fast reply.

I think that the TPS74401 has too much drive ability.

But I have never designed a USB circuit, so I suggest to my customer the TPS74401.

Thanks

Naoki
