ILC6660 Advance
CMOS Monolithic
Voltage Converter
General Description
The ILC6660 monolithic, charge-pump
voltage inverter converts a +1.
5V to +5.
5V input to a corresponding -1.
5V to -5.
5V output.
Using only two low-cost
capacitors, the charge pump's 100mA output replaces switching regulators, eliminating inductors and their associated cost, size, and EMI.
Greater than 90% efficiency over most of its load-current range combined with a typical operating current of only 120µA provides ideal performance for both battery-powered and board-level
voltage conversion applications.
The ILC6660 can also double or split the output
voltage of an input powered supply or battery...
