Outline of operation when multiplier has a
positive offset
(8)Restart timer
In steady state, set signals from the ZCD circuit turns
MOSFET on at each switching cycles. But a trigger
signal is needed when starting up or stabilizing
operation in the light load condition. This IC includes a
restart timer. If off period of output pulse continues
200s or more, it automatically generates a trigger
signal.
(9)Undervoltage lockout circuit
These IC contain an undervoltage lockout circuit to
prevent malfunction when the supply voltage drops.
When the supply voltage rises from 0V, FA5500A starts
operation at 11.5V(typ.) and FA5501A starts operation
at 13V(typ.). If the supply voltage drops after the IC
starts up, both IC stops operation at 9V(typ.). When IC
stops operation by undervoltage lock out circuit, OUT
pin voltage is kept in low state and the current
consumption of IC decreases below 20A.
(10)Output circuit
This IC contains a push-pull output stage and can
directly drive the MOSFET. The peak current of output
stage is sink: 1.0A (max.), source: 0.5A (max.)
