TPS62163: Output discharge function of TPS62163

Part Number: TPS62163
Other Parts Discussed in Thread: TLV62130A


I have a question for TPS62163 regarding output discharge function.'s list of DCDC said TPS62163 has output discharge function. However there is not on datasheet.

I found that PG pin can be used for output discharge on the datasheet of TLV62130A. can this usage apply for TPS62163?

And could you tell me how large current is acceptable for PG pin of TPS62163 and suggested resistor value?

Thank you and best regards,

  • Hello Kazuki,

    It seems there is a mix up between two parts on our website which will be fixed thanks to you. You are right TPS62163 does not have an output discharge function. I would recommend you take a look at the TPS62133/TPS62143 which do have this feature. 

    According to the output voltage of your system, you just need to make sure the maximum current into PG does not exceed 10mA. The more current will be discharged the faster your discharge will be. There is an example in the Topic 9.3.2 of this product Datasheet. 

    Thank you for your feedback!

    Best Regards,
