Boost Controller with

Power Factor Correction

FeaTures

DescripTion

The LT^®8312 is a power factor correction (PFC) boost

controller. A LT8312-based design can achieve a power

factorofgreaterthan0.99byactivelymodulatingtheinput

current,allowingcompliancewithmostHarmonicCurrent

Emission requirements.

Low Harmonic Distortion

Overvoltage Protection

Energy Star Compliant (<0.5W No-Load Operation)

16-Lead MSOP Package

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.
