Part Number: TPS92692

Dear TI Experts,

My customer has a requirmnet of 24V input, 30~50V output, 10A current boost LED driver, is it possible to use 2 paralleled  TPS92692 to make it?

If yes, could you kindly help to provide a similiar design to start? If no, could you kindly advice other solution for this requirment? Thanks a lot.

    Hi Bruce,

    You can do the design with just one TPS92692. The TPS92692 is a current controller and in reality the external components determine the output power level. For your application, the biggest issue is driving the external FET and the switching frequency that you use. With 500W design, the external FET can have high gate charge and you have to make sure that the gate drive of the TPS92692 can drive the FET at the frequency that you want to operate at.

    If the gate drive is not strong enough for the power FET or (FET's in parrallel) that you choose then you can use a stronger external FET driver to buffer the output prior driving the FET.

    Thanks Tuan
