The STMicroelectronics Power Factor Corrector IC provides the necessary features to achieve a very high power factor up to 0.99. Realized in BCD 60II technology this power factor corrector pre regulator contains all the control functions for designing a high efficiency mode power supply with sinusoidal line current consumption. It can be easily used in systems with mains voltages between 85V to 265V without any line switch.

Universal input mains

Average current mode for PWM for minimum noise sensitivity
