LM2685
Dual Output Regulated Switched Capacitor Voltage
Converter
General Description
The LM2685 CMOS charge-pump voltage converter oper-
ates 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 re-
duce output resistance and voltage ripple. With an operating
current of only 800A (operating efficiency greater than 80%
with most loads) and 6A typical shutdown current, the
LM2685 is ideal for use in battery powered systems. The
device is in a small 14-pin TSSOP package.
