TPS659037: SMPS3 3A vs 2A rating dependent on OTP

Part Number: TPS659037

Hi,

the TPS659037 datasheet says that SMPS is limited to 2A vs 3A, if input voltage is below vs above 3V. Is the SMPS3 rating dependent on the OTP?

Thanks,

--Gunter

    Hi Gunter,

    SMPS3 max current is not dependent on OTP, only the input voltage. Since the recommended operating voltage is 3.135V minimum, it can always operate with 3A max while operating within recommended operating conditions.

    SMPS6 has an OTP option for 2A vs. 3A, but all our OTP options are configured for 3A.

    Regards,
