Description
LMC7660 Switched Capacitor Voltage Converter April 1997 LMC7660 Switched Capacitor Voltage Converter General .
Features
* operation over full temperature and voltage range without need for an external diode, low quiescent current, and high power efficiency. The LMC7660 uses its built-in oscillator to switch 4 power MOS switches and charge two inexpensive electrolytic capacitors. Features n Operation over full temperaApplications
* Changing Oscillator Frequency It is possible to dramatically reduce the quiescent operating current of the LMC7660 by lowering the oscillator frequency. The oscillator frequency can be lowered from a nominal 10 kHz to several hundred hertz, by adding a slow-down capacitor Cosc (Figure 3). As shown iLMC7660 Distributors
