L4985 - CCM PFC controller

The L4985 is a peak current-mode PFC controller for boost converter with a proprietary multiplier “emulator” which in addition to the innovative THD optimizers guarantee very low Total Harmonic Distortion (THD) performance in all operating conditions.

The device comes in a pin SO package and offers

* Peak current mode CCM-operated

* 800 V high voltage startup with integrated input voltage sensing

* Active input filter capacitor discharge

* Proprietary multiplier “emulator” with minimum THD of line current in all operating conditions (CCM and DCM)

* Extre
