TPS2042B-Q1: capacitor value at out-pin

Yasushi Fujiwara

Part Number: TPS2042B-Q1

Hello Experts,

Regarding datasheet Figure 9-12/9-13, output capacitor value is 33uF per downstream port. But Note A mentioned "USB rev 1.1 requires 120 µF per hub". How customer choose a output capacitor value on OUT-pin? Customer should choose 120uF per downstream port? Or 33uF per downstream port is enough?

Best Regards,
Fujiwara

    Hi Fujiwara,

    If it's for hub application, it requires no less than 120uF.

    For others, it's according to customer's application.

    For TI's policy, I will first click resolved button.

    If you have any other concern, contact me any time.

    If you think resolved, please help click 'Issue is solved button'.

    Thanks.
