CAT660
CAT660 is 100mA CMOS Charge Pump Inverter/Doubler manufactured by onsemi.
100 m A 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 m A 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 k Hz) or low (10 k Hz) internal oscillator frequency, thus allowing quiescent current vs. capacitor size trade- offs to be made. The 80 k Hz 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 patible with the 7660/1044, offering an easy upgrade for applications with 100 m A loads.
