TPS63000: Is there any ESD protection diode from "EN" to "VIN" or "VINA" in TPS63000?

TPS63000: Peak Current Limit for Reverse Operation

Part Number: TPS63000
Other Parts Discussed in Thread: TPS63802

Hi expert,

I saw TPS63802 has Peak Current Limit for Reverse Operation of -0.9A. What is the definition of this spec? And, what is this value for TPS63000？

Thanks.

    Hi   Di,

    In PWM operation, when output voltage is higher than set one, there will be reverse current from output to input, TPS63802 limit the peak of reverse current to -0.9A.

    For TPS63000, i did not find such data. sorry for that. is this data is a must one from your side?

    Regards

    I'm thinking about upgrate to TPS63802 for smaller size，but not sure if TPS63802 can sink higher current than tps63000 @ Vout=1.2V. It seems TPS63802's -0.9A is higher than TPS63000's measured -0.6A. But, TPS63802 seems can just output 1.8V as the minimum output voltage.

    Hi  Di,

    correct, the minimum output voltage of TPS63802 is 1.8V. But the -0.9A is a value of peak current limit, for averange reverse current, it should be a smaller one.
