A charge pump is ideal for low voltage battery operation because the V
up to drive the LCD panel. The charge pump requires a charging capacitor and filter capacitor for
each of the LCD voltages as seen in Figure 25-12. These capacitors are typically low leakage
types such as polyester, polypropylene, or polystyrene material. Another feature that makes the
charge pump ideal for battery applications is that the current consumption is proportional to the
number of pixels that are energized.
