TPS62802: What is the minimum Vin for Vout of 3.3V

Part Number: TPS62802

The datasheet is not clear for the minimum Vin for a Vout of 3.3V for the TPS62802.

The datasheet says the minimum Vin is 1.8V, but since this is a Buck Supply that is not possible for this part. 

  • Hi,

    The datasheet describes the Vin for TPS6280x family in general. Hence, the input Voltage Range is from 1.8 V to 5.5 V. 

    Of course, it is required to have higher Vin for a buck converter. To get an output of 3.3V, it is required to set a higher Vin taking into consideration that we do not have 100% efficiency. It is not possible to specify any minimum Vin for a particular output voltage. This depends on the application mainly, the load conditions and the losses in the circuit. 

    I hope I could answer your question.

    Regards,
