TPS63700: The factor for DC output accuracy

Hirokazu Takahashi

Part Number: TPS63700

Hello Support team,

VOUT DC output accuracy is defined +/-3% as typ.
Does the error value cover Ta=–40~85°C?
What kind of factors are +/-3% contained in?
The variation of Vref, Vfb, Ta range and etc...

Best Regards,
Hirokazu

    Hi Hirokazu,

    According to the datasheet, this accuracy should be for typical conditions, therefore ambient temperature. But I will double check this. Normally, the biggest contributors to the output voltage accuracy should be the reference voltage accuracy (in this case around 1%), and the voltage divider resistors.

    Hi Hirokazu,

    We haven’t heard back so we're assuming this resolves your issue. If not, just post a reply below, or create a new thread if the thread has locked due to time-out.

    Thanks and regards,
