Part Number: LM5026
Hi team,
Could you please advise how to improve the thermal performance for the LM5026 design? Such as optimizing the setting, adding snubber or any other options.
The case temperature of main FET is up to 117C at room temperature and full load condition. Thanks for your support!
Please find the attached schematic and waveforms.
Spec: 12V to 54V/2.3A
Schematic:
1. changed MP1/MP2/MP3 to FDMS86200 to cover 110V Vds spike.
2. changed MP4 to Si7461DP for lower conduction loss.
