the average demand only. Therefore, the output capacitor
must absorb the difference between the delivered power
and the power consumed by the load. This means that when
the power fed to the load is lower than the demand, the
output capacitor discharges to compensate for the lack of
power. Alternatively, when the supplied power is higher
than that absorbed by the load, the output capacitor charges
to store the excess energy. The situation is depicted in
Figure 26.

As a consequence, the output voltage exhibits a ripple at
a frequency of either 100 Hz (for 50 Hz mains such as in
Europe) or 120 Hz (for 60 Hz mains in the USA). This
ripple must not be taken into account by the regulation loop
because the error amplifiers output voltage must be kept
constant over a given ac line cycle for a proper shaping of
the line current. Due to this constraint, the regulation
bandwidth is typically set below 20 Hz. For a simple type 1
compensation network, only a capacitor is placed between
FB and Control (see Figure 1). In this configuration, the
capacitor necessary to attenuate the bulk voltage ripple is
given by:

ON TIME SEQUENCE
Since the NCP1606 is designed to control a CRM boost
converter, its switching pattern must accommodate
constant on times and variable off times. The Controller
generates the on time via an external capacitor connected
to pin 3 (Ct). A current source charges this capacitor to a
level determined by the Control pin voltage. Specifically,
Ct is charged to V
