... A PPLICATI S I FOR ATIO Theory of Operation To understand the theory of operation of the LTC1046, a review of a basic switched capacitor building block is helpful. In Figure 2, when the switch is in the left position, capacitor C1 will charge to voltage V1. The total charge on C1 will C1V1. The switch then moves to the right, discharg- ing C1 to voltage V2 ...

... EQUIV fC1 Figure 3. Switched Capacitor Equivalent Circuit Examination of Figure 4 shows that the LTC1046 has the same switching action as the basic switched capacitor building block. With the addition of finite switch ON resistance and output voltage ripple, the simple theory, although not exact, provides an intuitive feel for how the device works ...

... This means that using a capacitor with 1 of ESR for C will have the same effect as increasing the output imped- ance of the LTC1046 This represents a significant increase in the voltage losses. For C is less dramatic. C ...
