TPS63001

Other Parts Discussed in Thread: TPS63001, TLV3011

Hi,

 

I'm currently  making a prototype design using one of your voltage regulator , the TPS63001(HIGH EFFICIENT SINGLE INDUCTOR BUCK-BOOST CONVERTER WITH 1.8-A SWITCHES). I would like to ask if it has an over voltage protection feature?

    No, this device does not have over voltage protection.  If it is operated in power save mode and the output voltage is too high, it will turn off until the output voltage decreases back down below regulation.

    Why do you need this feature?

    Thanks for the info. We need to put an OVP at the output of the regulator to protect the system connected to it in case an over voltage occur.

    We did not enable the power save mode just like the evaluation module of this IC. Do you have any application note showing how to embed an OVP circuit to this IC?

    The IC is designed to regulate the output voltage to a certain level as set by the FB pin resistor divider.  I don't think you need a separate OVP circuit.

    If you want one, you could have a simple comparator + reference that then pulls the EN pin low if the output voltage gets too high.  The TLV3011 would work for this purpose.
