LT3798/LT8309 5V, 2A Energy Star Compliant Isolated Converter

Jesus Rosales - Applications Engineer
Gabino Alonso - Strategic Marketing Engineer Feb 10th 2015
The focus of this circuirt was to take a design based on the LT®3798 and make it Energy Star Compliant; reduce no load, standby power to less than 300mW. That was achieved by adding the components highlighted in the dotted line box in the schematic inside the primary side. This circuit is simply a switch that removes ...

LT8302 8V to 32VIN/5VOUT Isolated Flyback Converter with LT8309

Nov 1st 2013
The LT®8302 is a monolithic micropower isolated flyback converter. By sampling the isolated output voltage directly from the primary-side flyback waveform, the part requires no third winding or opto-isolator for regulation. The output voltage is programmed with two external resistors and a third optional temperature compensation ...

LT3748/LT8309 40W, 5V Isolated Telecom Supply

Jul 20th 2010
The LT®8309 is a secondary-side synchronous rectifier driver that replaces the output rectifier diode in a flyback topology. By replacing the diode with a N-channel MOSFET, applications are no longer restricted by the heat constraints of the output diode. The IC replicates the behavior of a diode by sensing the drain-to-source ...
