What is the minimum input voltage required at input for PMIC TLF35584QVHS1 to operate in buck or step down regulator mode?

Level 1
Level 1

Functional range is defined from 6V to 40V. Whereas in Note/Test condition it is specified as greater than or equal to 6.5V.

Hello Lokesh,

The recommended minimum working voltage of the PMIC is 6V (without step up regulator), It may work below this voltage also. But below 6V we can't guarantee the datasheet parameters

In the above table, Vvs is 6.5V to generate the Vprereg =5.65 to 5.95 V. If Vvs is less than 6.5V then Vprereg also will be less and it may not be in the range of 5.65 to 5.95V for all the temperature ranges. That min and max values are derived for the entire temperature ranges.
