1 / 7 page 1 TM File Number 4835.1 CAUTION: These devices are sensitive to electrostatic discharge; follow proper IC Handling Procedures. 1-888-INTERSIL or 321-724-7143 | Intersil and Design is a trademark of Intersil Corporation. | Copyright © Intersil Corporation 2000 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 µA typical) make these devices ideal for both battery-powered and board-level voltage conversion applications.
