LT3752/LT8311 48Vin, 24Vout Active Clamp Forward Converter with High Light Load Efficiency

Fei Guo - Apps Engineer
Gabino Alonso - Strategic Marketing Engineer
Feb 11th 2015
The LT3752 includes a number of programmable features that make it suitable for this application. For instance, programmable delays between various gate signals is used to prevent cross-conduction and to optimize efficiency, and programmable turn-on current spike blanking (adaptive leading edge blanking plus programmable extended ...

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 ...
