LT3798 5V, 2A Energy Star Compliant Isolated Converter

Jesus Rosales - Applications Engineer Feb 10th 2015
The focus of this circuirt was to take a design based on the LT®3798 and make it Energy Star Compliant; reduce no load, standby power to less than 300mW. That was achieved by adding the components highlighted in the dotted line box in the schematic inside the primary side. This circuit is simply a switch that removes ...

LT3798 Universal Input 48W PFC Application

Dec 1st 2011
The LT3798 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 LT3798 based design can achieve a power factor of greater than 0.97 by actively modulating the input current, ...
