BASIC EXTERNAL CONNECTION
G
Voltage Doubler and Tripler
A doubled voltage can be obtained at V
OUT
CAP2-)
by disconnecting capacitor C
2
from the tripler
configuration and shorting CAP2- (pin4) and V
OUT
(pin 8).
G
Voltage Tripler+Regulator
V
reg
output is given a temperature gradient, after
boosted output V
OUT
regulated. In this connection,
both V
OUT
and V
reg
can be taken out at the same
time.
G
Parallel Connection
Parallel connection of n circuits can reduce R
OUT
to about
1/n, that output impedance R
OUT
can be reduced by
connecting serial configuraiton. A single smoothing
capacitor C
3
can be used commonly for all parallely
connected circuit.
In parallely connection, a regulated output can be
obtained by applying the regulation circuit to only one of
the n parallely connected circuit.
G
Cascade Connection
Cascade connection of SCI7661C
/
M (by connecting V
IN
and V
OUT
of one stage to V
DD
and V
IN
respectively of
the next stage) further increase the output voltage. Note, however, that the serial connection increases the
output impedance.
