Key Features
- Line-modulated fixed-off-time (LM-FOT) control of CCM-operated PFC pre-regulators.
- Proprietary LM-FOT modulator for nearly fixedfrequency operation.
- Proprietary multiplier design for minimum THD of AC input current.
- Fast “bi-directional” input voltage feedforward (1/V2 correction).
- Accurate adjustable output overvoltage protection.
- Protection against feedback loop failure (latched shutdown).
- Inductor saturation protection.
