Analog Devices LT8312

Description

The LT®8312 is a power factor correction (PFC) boost controller. A LT8312-based design can achieve a power factor of greater than 0.99 by actively modulating the input current, allowing compliance with most Harmonic Current Emission requirements.

The LT8312 is well suited for a wide variety of off-line applications. The input range can be scaled up or down, depending mainly on the choice of external components. Efficiencies higher than 95% can be achieved with output power levels up to 250W.
