Operation of Charge Pump Circuit
Initial charging
(1)
When RESET is released, T
r1
is turned ON and T
r2
turned OFF. Ccp 2 is charged from Ccp 2 via
Di1.
(2)
T
r1
is turned OFF, T
r2
is turned ON, and Ccp 1 is charged from Ccp 2 via Di2.
(3)
When the voltage difference between V
M
and V
H
(Ccp A pin voltage
=
charge pump voltage)
reaches V
DD
or higher, operation halts (Steady state).
Actual operation
(4)
Ccp 1 charge is used at f
chop
switching and the V
H
potential drops.
(5)
Charges up by (1) and (2) above.
