where R TRIM is the value of the trim resistor in k ? and
Δ V% is the absolute value of desired margining
expressed in percents of the nominal output voltage.
Resistance of the trim resistor is determined from the
equation below:
During normal operation the resistors are removed
from the circuit by the switches. The “Margining

where V OUT is the desired output voltage in Volts.
If the R TRIM is open or the TRIM pin is shorted to
PGND, the V OUT =0.5V.
9.2 Output Voltage Margining
Margining can be implemented by changing the
An alternative configuration of the margining circuit is
shown in Figure 14. In the configuration both
switches are normally open that may be
advantageous in some implementations.
