Характеристики
L4981BD, Контроллер коррекции коэффициента мощности, [SO-20]The L4981BD is a Power Factor Corrector provides the necessary features to achieve a very high power factor up to 0.99. Realized in BCD 60II technology this power factor corrector (PFC) pre-regulator contains all the control functions for designing a high efficiency-mode power supply with sinusoidal line current consumption. The L4981 can be easily used in systems with mains voltages between 85V to 265V without any line switch. This new PFC offers modulated frequency optimizing the size of the input filter
