LT8310  
100VIN Forward Converter  
Controller  
FeaTures  
DescripTion  
The LT®8310 is a simple-to-use resonant reset forward  
converter controller that drives the gate of a low side  
N-channel MOSFET from an internally regulated 10V sup-  
ply.TheLT8310featuresdutymodecontrolthatgenerates  
a stable, regulated, isolated output using a single power  
transformer. With the addition of output voltage feedback,  
viaopto-coupler(isolated)ordirectlywired(nonisolated),  
current mode regulation is activated, improving output  
accuracy and load response. The flexibility to choose  
transformer turns ratio makes high step-down or step-up  
ratios possible without operating at duty cycle extremes.

component size. A synchronous output is available for  
controlling secondary side synchronous rectification to  
improveefficiency.Userprogrammableprotectionfeatures  
include monitors on input voltage (UVLO and OVLO) and  
switch current (overcurrent limit). The LT8310 soft-start  
feature helps protect the transformer from flux saturation.
