To achieve the specs from the customer, they will need to redesign the transformer and update the primary/secondary power stage. …
Hello Sam,
1. GaN offers lower switching energy and better figure of merits compared to MOSFET and is expected to provide improvements in these types of application. You can further optimize this by the choice of switching frequency and magnetic design…
Hi Dhanasekar,
For LLC, you need to be able to push the switching frequency above resonance in order to get a well controlled, soft start. If the resonant frequency is too close to the max switching frequency of the IC, then you will likely run into…
Hi James,
Yes you could use two LMG5200 on the secondary side of the circuit for each of the synchronous rectification, or you can use a discrete driver with EPC FETs chosen according to your current level. LMG1020 and LMG1205 drivers, as well as UCD7138…
Hello Carlos,
I recommend you to check this online training video out at ti.com, which will answer most of your questions about TP PFC.
