LM2686
Regulated Switched Capacitor Voltage Converter
General Description
The LM2686 CMOS charge-pump voltage converter oper-
ates 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.
