APPLICATION INFORMATION
ADJUSTING THE OUTPUT VOLTAGE
The VADJ control sets the output voltage of the TPS84620. The output voltage adjustment range is from 1.2V 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 module. 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.

For other output voltages, the value of the required resistor can either be calculated using the following formula,
or simply selected from the range of values given in Table 2.
