Description
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.
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.
