ADI LT8310EFE#PBF

正向转换器控制器6V ~ 100V3.8 mA

Overview

The LT8310EFE#PBF 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 LT8310EFE#PBF 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.

The user can program the switching frequency from 100kHz to 500kHz to optimize efficiency, performance or external component size. A synchronous output is available for controlling secondary side synchronous rectification to improve efficiency. User programmable protection features include monitors on input voltage (UVLO and OVLO) and switch current (overcurrent limit). The LT8310EFE#PBF soft-start feature helps protect the transformer from flux saturation.
