7.3 Feature Description

7.3.1 Adjusting the Output Voltage

A resistor divider connected to the FB pin (pin 16) programs the output voltage of the LMZM33603. The output

voltage adjustment range is from 1 V to 18 V. (See Output Current vs Output Voltage for the maximum allowable

output voltage as a function of output current.) Figure 18 shows the feedback resistor connections for setting the

output voltage. The recommended value of RFBB is 10 kΩ. The value for RFBT can be calculated using

Equation 1. Depending on the output voltage, a feed-forward capacitor, CFF, may be required for optimum

transient performance. Table 1 lists the standard external RFBT and CFF values for several output voltages

between 2.5 V and 18 V. Table 2 lists the values for output voltages below 2.5 V. Additionally, Table 1 and

Table 2 include the recommended switching frequency (FSW), the frequency setting resistor (RRT), and the

minimum and maximum output capacitance for each of the output voltages listed.

For designs with RFBB other than 10 kΩ, adjust CFF and RFBT such that (CFF × RFBT) is unchanged and adjust

RFBT such that (RFBT / RFBB) is unchanged.
