1.2.3 VSET/MODE Resistor

R4 selects the MODE setting (PSM or FPWM) and output voltage setting configuration. When using the VSET configuration for setting the output voltage, short R1 and remove R2. See the TPSM8286x 4-A and 6-A High Efficiency Step-Down Converter QFN Power Module data sheet for details of the various settings.
