FEATURES  
DESCRIPTION  
The LM2686 CMOS charge-pump voltage converter  
2
+5V Regulated Output  
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  
450µA (operating efficiency greater than 80% with  
most loads) and 6.0µA typical shutdown current, the  
LM2686 is ideal for use in battery powered systems.  
The device is in a small 14-pin TSSOP package.
