voltage, the clocks are activated, switch S5 is disconnected
and the output voltage is the result of the C1 charge transfer
into the output load. The current is limited by three mains
parameters:
structure and size of the NMOS/PMOS devices used to
When the NCN6010 is programmed in the 5.0 V output
The first parameters are depending upon the internal
- the Ron of the switching MOS (S1 through S4)
- the operating frequency
- the C1/C2 ratio and their ESR

design the chip. The third parameter is adjustable by the user
and, beside the micro farad values, the type of capacitors
plays a significant role. As a matter of fact, using a low cost
electrolytic model will ruin the efficiency due to the high
ESR of such a capacitor. It is highly recommended to use
ceramic types, preferably from the X5R or X7R series, to
achieve the efficiency and the SIM_VCC output voltage
ripple. Table 2 summarizes the characteristics of the most
common type of capacitors.
