11.2.2.2.2
Programming The Output Voltage
In the adjustable output versions, an external resistor divider is used to adjust the output voltage. The resistor
divider must be connected between VOUT, FB and GND as shown in Figure 28. When the output voltage is
regulated properly, the typical voltage value at the FB pin is 500 mV for the adjustable devices. The maximum
recommended value for the output voltage is 6.0 V. The current through the resistor divider should be about 100
times greater than the current into the FB pin. The typical current into the FB pin is 0.01
μA, and the voltage
across the resistor between FB and GND, R2, is typically 500 mV. Based on those two values, the recommended
value for R2 should be lower than 500 kΩ, in order to set the divider current to 1 μA or higher. The value of the
resistor connected between VOUT and FB, R1, depending on the needed output voltage (VOUT), can be
calculated using Equation 5:
(5)
For this example, if an output voltage of 4.2 V is needed, a 1.2-M
Ω resistor is calculated for R1 when 160 kΩ is
selected for R2. This would yield an output voltage of 4.25 V, neglecting resistor tolerances.
11.2.2.2.3
Inductor Selection
See Inductor Selection for a discussion on inductor choice.
11.2.2.2.4
Capacitor Selection
The procedure for selecting capacitors is the same as for the fixed output voltage circuit. See Capacitor
Selection.
11.2.2.3 Application Curves
Figure 29 shows the excellent efficiency of the converter, which remains above 80% with heavily discharged
cells.
