LT LT3798MPMSE#TRPBF

隔离10V ~ 38V

Overview

The LT3798MPMSE#TRPBF is a constant-voltage/constant-current isolated flyback controller that combines active power factor correction (PFC) with no opto-coupler required for output voltage feedback into a single-stage converter. A LT3798MPMSE#TRPBF based design can achieve a power factor of greater than 0.97 by actively modulating the input current, allowing compliance with most Harmonic Current Emission requirements.

The LT3798MPMSE#TRPBF 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 86% can be achieved with output power levels up to 100W. In addition, the LT3798MPMSE#TRPBF can easily be designed into high DC input applications.
