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 V
bo
goes below than V
BOL
 (0.7 V typical), the device turns off
the Drive output and keeps it off till V
bo
 exceeds V
BOH
(1.3 V typical). When the device awakes after an offstate
(Undervoltage lockout or shutdown), the default threshold
is V
BOH
.
Overpower Limitation (OPL)
This is a second OCP with a threshold that is line
dependent. Sense current I
cs
 represents the inductor current
I
L
 and hence represents the input current approximately.
Input voltage signal V
bo
 represents the rms input voltage.
The product (I
cs
 ?V
bo
) represents an approximated input
power (I
L
 ?V
ac
). It is illustrated in Figure 46.

When the product (I
cs
 ?V
bo
) 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 (I
cs
 ?V
bo
) is lower than the
200 mVA level. This 200 mVA level corresponds to the
approximated input power (I
L
 ?V

) 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 V
cc
  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
lowvoltage bias supply voltage by adding an auxiliary
winding on the PFC boost inductor. Alternatively, it is
recommended to get the V
cc
  biasing supply from the
2
nd
stage power conversion stage.
