VboH / VboL
VboH = 1.3 V, VboL = 0.7 V
After Device Operates
Before Device Operates
Hence a larger hysteresis of the brown out comparator is
needed, which is 0.7 V typical in this device. When Vbo
goes below than VBOL (0.7 V typical), the device turns off
the Drive output and keeps it off till Vbo exceeds VBOH
(1.3 V typical). When the device awakes after an off−state
(Undervoltage lockout or shutdown), the default threshold
is VBOH.
Overpower Limitation (OPL)
This is a second OCP with a threshold that is line
dependent. Sense current Ics represents the inductor current
IL and hence represents the input current approximately.
Input voltage signal Vbo represents the rms input voltage.
The product (Ics ⋅ Vbo) represents an approximated input
power (IL ⋅ Vac). It is illustrated in Figure 46.

When the product (Ics ⋅ Vbo) is greater than a permissible
level 200
mVA, the device turns off the drive output so that
the input power is limited. The OPL is automatically
deactivated when the product (Ics ⋅ Vbo) is lower than the
200
mVA level. This 200 mVA level corresponds to the
approximated input power (IL ⋅ Vac) to be smaller than the
particular expression in (Equation 23).

Bias the Controller
It is recommended to add a typical 1 nF to 100 nF
decoupling capacitor next to the Vcc pin for proper
operation. When the NCP1654 operates in follower boost
mode, the PFC output voltage is not always regulated at a
particular level under all application range of input voltage
and load power. It is not recommended to make a
low−voltage bias supply voltage by adding an auxiliary
winding on the PFC boost inductor. Alternatively, it is
recommended to get the Vcc biasing supply from the
2nd−stage power conversion stage.
