Operation of Charge Pump Circuit
Initial charging
(1)
When RESET is released, Tr1 is turned ON and Tr2 turned OFF. Ccp 2 is charged from Ccp 2 via
Di1.
(2)
Tr1 is turned OFF, Tr2 is turned ON, and Ccp 1 is charged from Ccp 2 via Di2.
(3)
When the voltage difference between VM and VH (Ccp A pin voltage = charge pump voltage)
reaches VDD or higher, operation halts (Steady state).
Actual operation
(4)
Ccp 1 charge is used at fchop switching and the VH potential drops.
(5)
Charges up by (1) and (2) above.
