PIN DESCRIPTION
The descriptions of the pins are listed in Table 3-1.
TABLE 3-1:
PIN FUNCTION TABLE
3.1
First Charge Pump Capacitor (C1
-)
Negative connection for the charge pump capacitor
(flying capacitor) used to transfer charge from the input
source to a second charge pump capacitor. This
charge pump capacitor is used to double the input volt-
age and store the charge in the second charge pump
capacitor.
It is recommended that a low ESR (equivalent series
resistance) capacitor be used. Additionally, larger
values will lower the output resistance.
3.2
Second Charge Pump Capacitor
(C2
+)
Positive connection for the second charge pump
capacitor (flying capacitor) used to transfer charge from
the first charge pump capacitor to the output.
It is recommended that a low ESR (equivalent series
resistance) capacitor be used. Additionally, larger
values will lower the output resistance.
3.3
Second Charge Pump Capacitor
(C2
-)
Negative connection for the second charge pump
capacitor (flying capacitor) used to transfer charge from
the first charge pump capacitor to the output. Proper
orientation is imperative when using a polarized
capacitor.
3.4
Negative Output Voltage (VOUT
-)
Negative connection for the negative charge pump out-
put capacitor. The negative charge pump output capac-
itor supplies the output load during the first, third and
fourth phases of the switching cycle. During the second
phase of the switching cycle, charge is restored to the
negative charge pump output capacitor. The negative
output voltage magnitude is approximately twice the
input voltage.
It is recommended that a low ESR (equivalent series
resistance) capacitor be used. Additionally, larger
values will lower the output ripple.
3.5
Ground (GND)
Input zero volt reference.
3.6
Power Supply Input (VIN)
Positive power supply input voltage connection. It is
recommended that a low ESR (equivalent series resis-
tance) capacitor be used to bypass the power supply
input to ground (GND).
3.7
First Charge Pump Capacitor (C1
+)
Positive connection for the charge pump capacitor (fly-
ing capacitor) used to transfer charge from the input
source to a second charge pump capacitor. Proper
orientation is imperative when using a polarized
capacitor.
3.8
Positive Output Voltage (VOUT
+)
Positive connection for the positive charge pump out-
put capacitor. The positive charge pump output capac-
itor supplies the output load during the first, second and
third phases of the switching cycle. During the fourth
phase of the switching cycle, charge is restored to the
positive charge pump output capacitor. The positive
output voltage magnitude is approximately twice the
input voltage.
It is recommended that a low ESR (equivalent series
resistance) capacitor be used. Additionally, larger
values will lower the output ripple.
