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 a high performance/ low-component count solution for CCM-operated boost PFC pre-regulators in EN61000-3-2 and JEIDA-MITI compliant applications, in a power range that spans from few hundred W to some kW.
The device, thanks to a proprietary off-time modulator, operates in quasi-fixed frequency in all operating conditions.
