are available, via two circuit versions. The NCP1395A
features a large hysteresis to allow a classical startup
method with a resistor connected to the bulk capacitor.
Then, at the end of the startup sequence, an auxiliary
winding is supposed to take over the controller supply

voltage. To the opposite, for applications where the
resonant controller is powered from a standby power
supply, the startup level of the NCP1395B of 10 V typically
allows a direct a connection from a 12 V source. Simple
ON/OFF operation is therefore feasible.
