n Available in FE20 TSSOP with HV Pin Spacing 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 supply. The LT8310 features duty mode control that generates
a stable, regulated, isolated output using a single power
transformer. With the addition of output voltage feedback,
via opto-coupler (isolated) or directly wired (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. n Applications Industrial, Automotive and Military Systems 48V Telecommunication Isolated Power Supplies
