The output voltage adjustment range is from 0.6V to 5.5V. The adjustment method requires the addition of RSET, which sets the output voltage, the connection of SENSE+ to VOUT, and in some cases RRT which sets the switching frequency. The RSET resistor must be connected directly between the VADJ (pin 43) and AGND (pin 45). The SENSE+ pin (pin 44) must be connected to VOUT either at the load for improved regulation or at VOUT of the device. The RRT resistor must be connected directly between the RT/CLK (pin 35) and AGND (pin 34). Table 1 gives the standard external RSET resistor for a number of common bus voltages, along with the required RRT resistor for that output voltage. Table 1.
