Figure 22. Charging Mode
During the first half cycle, Q2 and Q3 transistors are turned on and flying capacitor, CF, will be charged to 2.5V
ideally.
Figure 23. Discharging Mode
During the second half cycle, Q1 and Q4 transistors are turned on. Capacitor CF will then be discharged to
output.
The output voltage can be calculated as follows:
Vout = VIN - VQ1 + V(CF) - VQ4 = VIN - VQ1 + 2.5V - VQ4 = 5 V. (Ideal)
The output voltage is regulated by output feedback and an internally compensated voltage control loop.
