    LT3573IMSE#PBF Product overview

    The LT3573IMSE#PBF is a monolithic Switching Regulator specifically designed for the isolated flyback topology. No third winding or opto-isolator is required for regulation. The part senses the isolated output voltage directly from the primary-side flyback waveform. A 1.25A/60V NPN power switch is integrated along with all control logic. The LT3573 operates with input supply voltages from 3 to 40V and can deliver output power up to 7W with no external power devices. The LT3573 utilizes boundary mode operation to provide a small magnetic solution with improved load regulation.

    LT3573EMSE#PBF Product overview

    The LT3573EMSE#PBF is an Isolated Flyback Converter without an opto-coupler specifically designed for the isolated flyback topology. No third winding or opto-isolator is required for regulation. The part senses the isolated output voltage directly from the primary-side flyback waveform. The LT3573 operates with input supply voltages from 3 to 40V and can deliver output power up to 7W with no external power devices. The LT3573 utilizes boundary mode operation to provide a small magnetic solution with improved load regulation. It derives its information about the isolated output voltage by examining the primary-side flyback pulse waveform. Due to the sampling nature of the feedback loop, there are several timing signals and other constraints that are required for proper LT3573 operation.
