CAT660 100 mA CMOS Charge Pump Inverter/Doubler Description The CAT660 is a charge−pump voltage converter. It will invert a 1.5 V to 5.5 V input to a −1.5 V to −5.5 V output. Only two external capacitors are needed. With a guaranteed 100 mA output current capability, the CAT660 can replace a switching regulator and its inductor. Lower EMI is achieved due to the absence of an inductor. In addition, the CAT660 can double a voltage supplied from a battery or power supply. Inputs from 2.5 V to 5.5 V will yield a doubled, 5 V to 11 V output voltage. A Frequency Control pin (BOOST/FC) is provided to select either a high (80 kHz) or low (10 kHz) internal oscillator frequency, thus allowing quiescent current vs. capacitor size trade−offs to be made.
