My customer is evaluating EMI with additional boot resister.
VCBOOT_UVLO datasheet spec is min 1.6V, typ 2.2V, max 2.7V, and VCC spec is typ 3.27V.
They have to avoid boot UVLO so they want to make sure the voltage at CBOOT - SW always higher than VCBOOT_UVLO range. But since there is a diode between VCC and CBOOT, 3.27V - Vf is already very close to 2.7V.
Could you provide VCBOOT_UVLO temperature characteristics?
I guess VCBOOT_UVLO has temperature drift to fit with Vf's temperature drift and, they can use 2.2V instead of 2.7V in 25degC condition.
