Charge Pump Capacitor (CAP + )
3.5
Low Voltage Pin (LV)
Positive connection for the charge pump capacitor, or
flying capacitor, used to transfer charge from the input
source to the output. In the voltage-inverting configura-
tion, the charge pump capacitor is charged to the input
voltage during the first half of the switching cycle. Dur-
The low voltage pin ensures proper operation of the
internal oscillator for input voltages below 3.5V. The low
voltage pin should be connected to ground (GND) for
input voltages below 3.5V. Otherwise, the low voltage
pin should be allowed to float.
ing the second half of the switching cycle, the charge
pump capacitor is inverted and charge is transferred to

Oscillator Control Input (OSC)
the output capacitor and load.
It is recommended that a low ESR (equivalent series
resistance) capacitor be used. Additionally, larger
values will lower the output resistance.
3.2 Ground (GND)
Input and output zero volt reference.
The oscillator control input can be utilized to slow down
or speed up the operation of the TC7660. Refer to
frequency.
3.7 Power Supply (V + )
3.3
Charge Pump Capacitor (CAP - )
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).
3.4
Output Voltage (V OUT )
Negative connection for the charge pump output
capacitor. In the voltage-inverting configuration, the
charge pump output capacitor supplies the output load
during the first half of the switching cycle. During the
second half of the switching cycle, charge is restored to
the charge pump output capacitor.
It is recommended that a low ESR (equivalent series
resistance) capacitor be used. Additionally, larger
values will lower the output ripple.
