trol functions for designing a high efficiency-mode  
power supply with sinusoidal line current con-  
sumption.  
The L4981 can be easily used in systems with  
mains voltages between 85V to 265V without any  
line switch. This new PFC offers the possibility to  
work at fixed frequency (L4981A) or modulated  
frequency (L4981B) optimizing the size of the in-  
DESCRIPTION  
The L4981 I.C. provides the necessary features  
to achieve a very high power factor up to 0.99.  
Realized in BCD 60II technology this power factor
