ICL7660CB Datasheet

Charge Pumps


The Intersil ICL7660 and ICL7660A are monolithic CMOS power supply circuits which offer unique performance advantages over previously available devices. The ICL7660 performs supply voltage conversions from positive to negative for an input range of +1.5V to +10.0V resulting in complementary output voltages of -1.5V to -10.0V and the ICL7660A does the same conversions with an input range of +1.5V to +12.0V resulting in complementary output voltages of -1.5V to -12.0V. Only 2 noncritical external capacitors are needed for the charge pump and charge reservoir functions.The ICL7660 and ICL7660A can also be connected to function as voltage doublers and will generate output voltages up to +18.6V with a +10V input. ICL7660CB Features • Simple Conversion of +5V Logic Supply to ±5V Supplies• Simple Voltage Multiplication (VOUT = (-) nVIN)• Typical Open Circuit Voltage Conversion Efficiency 99.9%• Typical Power Efficiency 98%• Wide Operating Voltage Range - ICL7660 . . . . . . . . . . . . . . . . . . . . . . . . . . 1.5V to 10.0V - ICL7660A . . . . . . . . . . . . . . . . . . . . . . . . . 1.5V to 12.0V• ICL7660A 100% Tested at 3V• Easy to Use - Requires Only 2 External Non-Critical Passive Components• No External Diode Over Full Temp. and Voltage Range• Pb-Free Plus Anneal Available (RoHS Compliant) ICL7660CB Applications • On Board Negative Supply for Dynamic RAMs• Localized μProcessor (8080 Type) Negative Supplies• Inexpensive Negative Supplies• Data Acquisition Systems
