1 / 5 page Ordering Information* TA = 40°C to = 85°C ILC6660IK 8-pin SOIC The ILC6660 monolithic, charge-pump voltage inverter con- verts 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 com- bined 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 dou- ble 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 qui- escent current. The Oscillator frequency can also be driven with an external clock. The ILC6660 is available in both 8-pin DIP and small-outline packages in commercial and extended temperature ranges.
