Q: TPS61220 switching frequency by 1158151
The information about the TPS61220's switching freqency. How about the range of the switching frequency?
A: Re: TPS61220 switching frequency and Iq by 1090425
The TPS61220 is not a fixed frequency converter. It operates by regulating the ripple current in the inductor to about 200 mA. The frequency then depends on the inductor value used. An equation for the switching frequency is given on page 14 of the datasheet.
