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.
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.
Adjust the voltage level of your devices with this step down LT3573EMSE#TRPBF DC to DC converter from Linear Technology. This converter"s single output can produce a current up to 1.85 A. It only needs a voltage of at least 3 V while not exceeding 40 V to effectively power your circuit. With a fixed output that has a voltage of 1.23 V, this is power management at its best. It has a switching frequency of 1000(Typ) kHz. Tape and reel packaging will encase this product during shipment, in order to ensure safe delivery and enable quick mounting of components. This converter has a minimum operating temperature of -40 °C and a maximum of 125 °C.
