PFC Boost Controller Improves Efficiency

PFC Boost Controller Improves Efficiency
Linear Technology Corp.

The LT8312 power factor correction (PFC) boost controller achieves a power factor of greater than 0.99 by actively modulating the input current, allowing compliance with most harmonic current emission requirements. The device operates with current mode control and critical conduction mode, which is a variable frequency switching scheme that returns the current to zero in the inductor with every cycle. This switching behavior is similar to zero voltage switching, which minimizes the electromagnetic interference and energy lost in the power switch, improving efficiency as much as 5%. Available in a 16-lead MSOP, price starts at $2.25 each/1,000. A datasheet is available at http://www.linear.com/product/LT8312
