SP6661
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
μ
SOIC packages.
