ICL828
Switched-Capacitor Voltage Inverter
The ICL828 IC performs supply voltage conversions from
positive to negative for an input range of +1.5V to +5.5V
resulting in complementary output voltages of -1.5V to -5.5V.
The ICL828 has a 12kHz internal oscillator and requires two
capacitors to invert the supply voltage. Cascading may be
made to increase the output voltage. The high efficiency
(greater than 90% over most of the load-current range) and
low operating current (60
μ
A typical) make these devices
ideal for both battery-powered and board-level voltage
conversion applications.
