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 L can be easily used in systems with mains voltages between 85V to V without anyline switch. This new PFC offers the possibility to work at fixed frequency LA or modulated frequency LB optimizing the size of the input filter; both the operating frequency modes working with an average current mode PWM controller, maintaining sinusoidal line current without slope compensation.


Besides power MOSFET gate driver, precise voltage reference externally availableerror amplifier, under voltage lockout, current sense and the soft start are included. To limit the number of the external components, the device integrates protections as overvoltage and overcurrent. The overcurrent level can be programmed using simple catasheet for LA. For a better precision and for LB an external divider must be used. Support Center Complete list and gateway to support datasheeh and resource pools.
