Product Overview CAT660: Charge Pump Voltage Converter For complete documentation, see the data sheet Product Description The CAT660 is a charge-pump voltage converter. It will invert a 1.5V to 5.5V input to a -1.5V to -5.5V output. Only two external capacitors are needed. With a guaranteed 100mA 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 2.5V to 5.5V will yield a doubled, 5V to 11V output voltage. A Frequency Control pin (BOOST/FC) is provided to select either a high (80kHz) or low (10kHz) internal oscillator frequency, thus allowing quiescent current vs. capacitor size trade-offs to be made. The 80kHz frequency is selected when the FC pin is connected to V+. The operating frequency can also be adjusted with an external capacitor at the OSC pin or by driving OSC with an external clock. 8-pin SOIC package is available in the industrial temperature range. The CAT660 replaces the MAX660 and the LTC®660. In addition, the CAT660 is pin compatible with the 7660/1044, offering an easy upgrade for applications with 100mA loads.
