Overview
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.
The 80 kHz 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 100 mA loads.
