I'm working with a buck converter (RT8298ZSP -- see page 11) that features an enable pin allowing programmed undervoltage lockout (UVLO). I have no problem programming the UVLO threshold...
Is there a relatively simple way to accomplish this?
Thanks.
NOTE: The data sheet is somewhat contradictory as to the actual enable comparator threshold voltage. In some places it's 1.7V; in others it's 2V. I emailed the manufacturer and was told that 2V is the correct value, despite the example given on page 11.
Ren1=100k
Ren2=18.2k
UVLO≈13V
...but I'd like to add about ±200mV of hysteresis (13.2V rising, 12.8V falling).Ren2=18.2k
UVLO≈13V
