6 FAQs about [How to choose the model of switching capacitor]
How to select input capacitors?
The first objective in selecting input capacitors is to reduce the ripple voltage amplitude seen at the input of the module. This reduces the rms ripple current to a level which can be handled by bulk capacitors. Ceramic capacitors placed right at the input of the regulator reduce ripple voltage amplitude.
How do I choose a capacitor?
Depending on what you are trying to accomplish, the amount and type of capacitance can vary. The first objective in selecting input capacitors is to reduce the ripple voltage amplitude seen at the input of the module. This reduces the rms ripple current to a level which can be handled by bulk capacitors.
How many Ma can a switched capacitor inverter run?
Typical IC switched capacitor inverters have maximum output currents of about 150mA maximum. Switched capacitor voltage converters do not maintain high efficiency for a wide range of ratios of input to output voltages, unlike their switching regulator counterparts.
Which capacitors are suitable for switching voltage regulator circuits?
Ceramic and tantalum capacitors are both suitable as input capacitors for switching voltage regulator circuits. Choose ceramic capacitors with a voltage rating of at least 1.5 times the maximum-input voltage. If tantalum capacitors are selected, they should be chosen with a voltage rating of at least twice the maximum-input voltage.
What is a switched capacitor voltage converter?
The two most common switched capacitor voltage converters are the voltage inverter and the voltage doublercircuit shown in Figure 4.1. In the voltage inverter, the charge pump capacitor, C1, is charged to the input voltage during the first half of the switching cycle.
What is a switched capacitor inverter?
Switched capacitor inverters are low cost and compact and are capable of achieving efficiencies greater than 90%. Obviously, the current output is limited by the size of the capacitors and the current carrying capacity of the switches. Typical IC switched capacitor inverters have maximum output currents of about 150mA maximum.
