LT8312HMS#PBF

Power factor correction (PFC) is a term for an electrical engineering technique used to overcome the power factor limitations associated with the use of alternating current (AC) power sources. It typically refers to the process of rectifying AC power to DC power in order to allow for voltage regulation for greater control over the power source. For example, using PFC, a power supply unit (PSU) can be used to eliminate the issues of flicker, over-voltage, or under-voltage, among other issues. The LT8312HMS#PBF is such an integrated power factor correction (PFC) integrated circuit that is widely used in many products ranging from consumer embedded solutions to industrial automation solutions.

The LT8312HMS#PBF is designed specifically for high power efficiency in applications such as medical, industrial, and telecom applications. It integrates two low side MOSFETs and one high current output inductor in a tiny, low-footprint package. Its high power density is achieved by a proprietary on-chip compensation technique to enable a fast transient response and steady-state performance.

The LT8312HMS#PBF also features a unique power factor correction (PFC) topology that is both efficient and robust.
