Control
The regulation block output is available on this pin. A compensation network is placed between FB
and Control to set the loop bandwidth low enough to yield a high power factor ratio and a low THD.

Ct
The Ct pin sources a 270 mA current to charge an external timing capacitor. The circuit controls the power
switch on time by comparing the Ct voltage to an internal voltage derived from the regulation block.

Cost Effective Power Factor Controller
The NCP1606 is an active power factor controller specifically designed for use as a pre−converter in electronic ballasts, ac−dc adapters and other medium power off line converters (typically up to 300 W). It embeds a Critical Conduction Mode (CRM) scheme that substantially exhibits unity power factor across a wide range of input voltages and power levels. Housed in a DIP8 or SOIC−8 package, the NCP1606 minimizes the number of external components. Its integration of comprehensive safety protection features makes it an excellent driver for rugged PFC stages.
