* Selectable Charge Pump Frequency of 25 kHz or 135 kHz;
Optim.
where higher oscillator frequency and smaller capacitors are needed. In addition, the CAT661 is pin compatible with the .
The CAT661 is a charge−pump voltage converter. It can invert a
positive input voltage to a negative output. Only two external capacitors are needed. With a guaranteed 100 mA output current capability, the CAT661 can replace a switching regulator and .
