ADP3607
Regulated Adjustable Output Voltage
For the adjustable version of the ADP3607, the regulated out-
put voltage is programmed by a resistor that is inserted between
the V
herent limit of the output voltage of a single doubling charge
pump stage is two times the input voltage. The scaling factor of
2.00 is reduced somewhat due to losses that increase with out-
put current. To increase the scaling factor to attain a more
positive output voltage, an external pump stage can be added
with just passive components as shown in Figure 20. That single
stage increases the scaling factor to a limit of 3, although the
diode drops will limit the ability to noticeably attain that exact
3.00 scaling factor. Even further increases can be achieved
with more external pump stages. High accuracy on the adjust-
able output is achieved through the use of precision trimmed
internal resistors, which eliminates the need to trim the external
resistor or add a second resistor to form a divider. The adjust-
able output voltage is set using the following formula:
