The LM2686 CMOS charge-pump voltage converter operates as an input voltage doubler and a +5V regulator for an input voltage in the range of +2.85V to +6.5V. Three low cost capacitors are used in this circuit to provide up to 50mA of output current at +5.0V (± 5%). The LM2686 operates at a 130 kHz switching frequency to reduce output resistance and voltage ripple. With an operating current of only 450A (operating efficiency greater than 80% with most loads) and 6.0A typical shutdown current, the LM2686 is ideal for use in battery powered systems. The device is in a small 14-pin TSSOP package.
