DESCRIPTION
The SP6661 is a CMOS DC-DC Monolithic Voltage Converter that can be implemented as a
Voltage Inverter or a Positive Voltage Doubler. As a Voltage Inverter, a -1.5V to -5.0V output can
be converted from a +1.5V to +5.0V input. As a Voltage Doubler, a +5.0V to +10.0V output can
be provided from a +2.5V to +5.0V input. The SP6661 is ideal for both battery-powered and board
level voltage conversion applications with a typical operating current of 3mA and a high efficiency
(>90%) over most of its load-current range. Typical end products for this device are disk drive
supplies, operational amplifier and interface power supplies, medical instruments, and hand held
and laptop computers. The SP6661 is available in 8-pin NSOIC, and µSOIC packages.

Description
Frequency Control for the internal oscillator. FC = open,
fosc = 120kHz typical; FC = V+ fosc = 900kHz typical.
Connect to the positive terminal of the charge pump capacitor.
(Voltage Inverter Circuit) Ground.
(Positive Voltage Doubler Circuit) Positive supply voltage
input.
Connect to the negative terminal of the charge pump capacitor.
(Voltage Inverter Circuit) Negative voltage output pin.
(Positive Voltage Doubler Circuit) Ground pin for power
supply.
Low -voltage operation input pin in 660 circuits. In SP6661
circuits can be connected to GND, OUT or left open as desired
with no effect.
Control pin for the oscillator. Internally connected to 15pF
capacitor. An external capacitor can be added to slow the
oscillator. Be careful to minimize stray capacitance. An
external oscillator can be connected to overdrive the OSC pin.
(Voltage Inverter Circuit) Positive voltage input pin for the
power supply.
(Positive Voltage Doubler Circuit) Positive voltage output.
