Switched-Capacitor Voltage Inverters
Shutdown Control
For a similar device with logic-controlled shutdown,
please refer to the MAX1720/MAX1721. To add manual
INPUT
shutdown control to the MAX870/MAX871, use the circuit
in Figure 8. The output resistance of the MAX870/
MAX871 will typically be 20 ? plus two times the output
resistance of the buffer driving IN. The 0.1μF capacitor at
the IN pin absorbs the transient input currents of the
MAX870/MAX871.

The output resistance of the buffer driving the IN pin
C2
can be reduced by connecting multiple buffers in par-
allel. The polarity of the shutdown signal can also be
changed by using a noninverting buffer to drive IN.
