Output Voltage Setpoint

To change the output voltage of the EVMs, it is necessary to change the value of resistor R5. Changing the value of R5 can change the output voltage above 0.6 V. The value of R5 for a specific output voltage can be calculated using Equation 1.

Equation 1. GUID-EDE6E8D9-0599-4F72-8EFF-58260DC8403C-low.gif

Table 3-1 lists the R5 values for some common output voltages. Note that the values given in Table 3-1 are standard values and not the exact value calculated using Table 3-1.
