TPS54495: Minimum input voltage for 5V output?

Part Number: TPS54495

Hi,

my customer would like to know the minimum input voltage for 5V output. the datasheet shows the input vs output voltage for 3.3V which gives a minimum input voltage of around 4.5V. Do you have the input vs output voltage graph for 5V output?

Thanks,

Kevin

    Hi Kevin,

    I tested with EVM. It shows that:

    For CH2 2A loading, the Vin>=7V for 5Vout.

    For CH1 4A loading, the Vin>=8V for 5Vout. Because when Vin=7V or 7.5V, it will be easy to trigger over temp protection.

    So what is the loading in your application?

    Thanks,
