Other Parts Discussed in Thread: UCC28911, UCC28881

Customer is looking for alternative solution to On-Semi's FSL336LRN.

Can you help to suggest if we have similar device? even non-p2p is acceptable. Thanks.

    Hi Yu-Chen,

    Could you please share some of the specifications for your design? We should be able to provide you with a good alternative solution suggestion if we know the following specifications:

    - Input Voltage Range

    -Output Power and Voltage

    -Desired Switching Frequency

    -Design Topology (Flyback or Buck)

    We are also happy to provide alternative topology suggestions besides Flyback or Buck once given your design specifications.

    Thanks.

    Hi Yu-Chen,

    We have not yet heard back from you regarding the design specifications. While we can provide a better alternative suggestion if we have the mentioned specifications, I can point you to the UCC28881 offered by TI. It is a PWM controller with integrated FET that supports buck and flyback topologies similar to the FSL336LRN, but be aware of the lower output power of the device. If your application requires higher power, I recommend looking into the UCC28911, another switching controller with integrated FET, which exclusively supports flyback topologies. If these are satisfying alternatives, please let us know so that we may mark this thread as resolved. Otherwise, please let us know some of the design specifications, and we can provide more tailored alternative solutions.

    Thanks.
