In voltage doubler configuration, the maximum V
ON
is as given by the following equation:
V
ON_MAX(2x)
For Voltage Tripler using additional external diodes and capacitors (Figure 18B):
V
ON
output voltage is determined by the following equation:
Negative Charge Pump Design Consideration
The negative charge pump consists of an internal switcher
M1, M2 which drives external steering diodes Dx and Dx via
a pump capacitor (CN) to generate the negative V
OFF
supply. An internal comparator (A1) senses the feedback
voltage on FBN and turns on M1 for a period up to half a
CLK period to maintain V
(FBN)
in regulated operation at
0.5V. External feedback resistor R5 is referenced to V
REF
.
