1 / 16 page  1 FEATURES s Replaces MAX660 and LTC®660 s Converts V+ to V- or V+ to 2V+ s Low output resistance, 4 Ω typical s High power efficiency s Selectable charge pump frequency - 10kHz or 80kHz - Optimize capacitor size 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. CAT660 100mA CMOS Charge Pump Inverter/Doubler s Low quiescent current s Pin-compatible, high-current alternative to 7660/1044 s Industrial temperature range s Available in 8-pin SOIC and DIP packages - Lead-free, halogen-free package option © Catalyst Semiconductor, Inc. Characteristics subject to change without notice Doc. No. MD-5000, Rev. W APPLICATIONS s Negative voltage generator s Voltage doubler s Voltage splitter s Low EMI power source s GaAs FET biasing s Lithium battery power supply s Instrumentation s LCD contrast bias s Cellular phones, pagers TYPICAL APPLICATION 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. Both 8-pin DIP and SOIC packages are 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.
