bridge applications and especially resonant half bridge
applications. The IC includes several features that help the
designer to cope with resonant SPMS design. All features
are described thereafter:

The NCP1392 is primarily intended to drive low cost half
Wide Operating Frequency Range: The internal
current controlled oscillator is capable to operate over
wide frequency range up to 250 kHz. Minimum
frequency accuracy is $3%.
Fixed Dead−Time: The internal dead−time helping to
fight with cross conduction between the upper and
lower power transistors. Three versions with different
dead time values are available to cover wide range of
applications.
100 ms PFC Timer: Fixed delay is placed to IC
operation whenever the driver restarts (VCC
BO_OK detect events). This delay assures that the bulk
voltage will be stabilized in the time the driver provides
pulses on the outputs. Another benefit of this delay is
that the soft start capacitor will be full discharged
before any restart.
Brown−Out Detection: The BO input monitors bulk
voltage level via resistor divider and thus assures that
the application is working only for wanted bulk voltage
band. The BO input sinks current of 18.2 mA until the

Current Controlled Oscillator
circuitry allowing operation from 50 kHz up to 500 kHz.
However, as a division by two internally creates the two Q
and Q outputs, the final effective signal on output Mlower
and Mupper switches between 25 kHz and 250 kHz. The
VCO is configured in such a way that if the current that flows
out from the Rt pin increases, the switching frequency also
goes up. Figure 22 shows the architecture of this oscillator.

Non−Latched Enable Input: The enable comparator
input is connected in parallel to the BO terminal to
allow the designer stop the output drivers when needed.
There is no PFC delay when enable input is released so
skip mode for resonant SMPS applications and
dimming for light ballast applications are possible.

Low Startup Current: This device features maximum
startup current of 50 mA which allows the designer to
use high value startup resistor for applications when
driver is supplied from the auxiliary winding. Power
dissipation of startup resistor is thus significantly
reduced.
