Figure 11. Step-Up Converter (Note 5)
Note 5: This is a typical step-up converter configuration. In the steady state, if the resistor divider voltage at pin
5 is greater than the voltage in the non-inverting input, which is 1.25V determined by the internal reference, the
output of the comparator will go low. At the next swithching period, the output switch will not conduct and the
output voltage will eventually drop below its nominal voltage until the divider voltage at pin 5 is lower than 1.25V.
Then the output of the comparator will go high, the output switch will be allowed to conduct. Since V
