Dual Output Regulated Switched Capacitor Voltage Converter

The LM2685 CMOS charge-pump voltage converter operates as an input voltage doubler, +5V Regulator and inverter for an input voltage in the range of +2.85V to +6.5V. Five low cost capacitors are used in this circuit to provide up to 50mA of output current at +5V ( 5%), and 15mA at -5V. The LM2685 operates at a 130 kHz switching frequency to reduce output resistance and voltage ripple. With an operating current of only 800?A (operating efficiency greater than 80% with most loads) and 6?A typical shutdown current, the LM2685 is ideal for use in battery powered systems. The device is in a small 14-pin TSSOP package.
