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, providing +9.5V or +2.3V at 100mA from a +5V input.
A frequency control (FC) pin selects either 5kHz typ or 50kHz typ (30kHz min) operation to optimize capacitor size and quiescent current. The Oscillator frequency can also be driven with an external clock. The ILC6660 is available in both 8-pin ...
