Linear Technology LT8310

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.

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 supply. The user can program the switching frequency from 100kHz to 500kHz to optimize efficiency, performance or external component size.
