EN/UVLO in LT3790 Parallel Buck-Boost Regulator

Category: Hardware
Product Number: LT3790

Hi,

Would there be any issues if I were to use only one resistive divider instead of two identical ones to program the EN/UVLO pin, and connect it to the second parallel regulator on page 24 of the datasheet?

Thanks,

Hello,

It can work. But you will have a larger hysteresis since there will be two 3uA pull-down current. So, you should take note of that.
