4.1.2 VSET/MODE Resistor (TPSM82866AA0PEVM Only)

R4 selects the MODE setting (PFM or FPWM) and output voltage setting configuration. When using the VSET configuration for setting the output voltage, short R1 and remove R2. See the TPSM82864A, TPSM82866A 2.4V to 5.5V Input, 4A/6A Step-Down Power Module With an Integrated Inductor in a Thin Overmolded QFN Package and MagPack™ Package data sheet for details of the various settings.
