Output voltage at adjustable version - feedback divider
The output voltage is sensed either by an internal voltage divider connected to the VOUT
pin (TLE6389G50-1 and TLE6389G50, fixed 5V versions) or an external divider from the
Buck output voltage to the FB pin (TLE6389GV, adjustable version).
To determine the resistors of the feedback divider for the desired output voltage VOUT at
the TLE6389GV select RFB2 between 5k and 500k and obtain RFB1 with the following
formula:
VFB is the threshold of the error amplifier with its value of typical 1.25V which shows that
the output voltage can be adjusted in a range from 1.25 to 15V. Keep in mind that the
current consumption will be increased in PFM mode in the range between 1.25 and 7V.
To filter spikes at the FB input connect a small ceramic cap (10nF) in parallel to RFB2.
