7.3.1 Adjusting the Output Voltage

A resistor divider connected to the FB pin (pin 9) sets the output voltage of the TPSM53604. The output voltage adjustment range is from 1 V to 7 V. Figure 7-1 shows the feedback resistor connections for setting the output voltage. The recommended value of RFBT is 10 kΩ. Use Equation 1 to calculate the value for RFBB. Table 7-1 lists the standard resistor values for several output voltages. The minimum required output capacitance for each output voltage is also included in Table 7-1. The capacitance values listed represent the effective capacitance, taking into account the effects of DC bias and temperature variation.
