TPS63060: Failure conditions

Part Number: TPS63060

Hello,

A few questions on potential problems with this device, for system understanding:

1. What happens if the PS/SYNC pin is left floating?

2. What happens if there is no capacitor on VAUX and the pin is left floating?

3. What happens if VAUX pin is shorted to ground? Is there internal short circuit protection?

Thanks,

Michael

  • Hi Michael,

    1. What happens if the PS/SYNC pin is left floating?

    A: instable PFM/PWM working. no damage to device.

    2. What happens if there is no capacitor on VAUX and the pin is left floating?

    A:device will work incorrectly because Vaux is instable. because current into Pin Vaux is not a stable one. Maybe there will be some damage.

    3. What happens if VAUX pin is shorted to ground? Is there internal short circuit protection?

    A:No SCP fro VAUX and device will be no switching.

    Regards
