Figure 22. Typical Operating Circuit
For the maximum output current and best performance, five ceramic capacitors of 1
F are recommended. For
lower currents or higher allowed output voltage ripple, other capacitors can be used. It is recommended that the
input and output capacitors have a minimum value of 1
F. This value is necessary to assure a stable operation
of the system due to the linear mode. With flying capacitors lower than 1
F, the maximum output power
decreases. This means that the device works in the linear mode with lower output currents.
output filter design
The power-good output is capable of driving light loads up to 5 mA (see Figure 23). Therefore, the output
resistance of the power-good pin with the output capacitor, can be used as an RC-filter.
