Generating Negative Supply using the ICL7660 Circuit Schematic and Datasheet
Generating Negative Supply using the ICL7660 Circuit Schematic and Datasheet - Since the ICL7135 is designed to work from less more 5V supplies, if you need to generate a negative supply you may negative supply circuit using ICL7660use the ICL7660 CMOS Voltage Converters for that IC.
This ICL7660 can also be connected to function as voltage doublers and will generate output voltages up to +18.6V with a +10V input.
For generating a negative supply, it can be performed with an ICL7660 and two 10 uF capacitors as shown in the schematic diagram.
This IC can also be used in applications such as On Board Negative Supply for Dynamic RAMs, Inexpensive Negative Supplies, Localized Micro Processor (8080 Type) Negative Supplies, and Data Acquisition Systems, according to the datasheet.
Detailed information about this CMOS Voltage Converters IC can be seen in the ICL7660 datasheet (source: intersil.com)
