L4986 Product details

Description

The L4986 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.

Features

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).
Extremely few external components.
Protections: feedback loop failure, OVP, OCP, inductor saturation, brown-in, brownout (compliant to medical SMPS standards).
Inductor current sense.
