increase the SIM_VCC voltage up to 5.0 V from a 3.3 V
typical battery. The concept, depicted in Figure 9, charges
the transfer capacitor C1 up to the Vcc value, then connects

theoretically, twice the battery voltage, but the system must

switches and the internal ohmic drops.
clocks are inactive and the load is directly connected to the
battery by means of switch S5. The SIM_VCC voltage
follows the input value, minus the drop coming from the
internal resistance . The current is limited by the Ron of the
power device S5 and t he output voltage will decrease as the
load current increases above 20 mA (typical). Figure 10
illustrates the theoretical waveforms.
