  • LM3152: FET failure

    Resolved
    Part Number: LM3152 Other Parts Discussed in Thread: CSD17527Q5A We are using an LM3152MH-3.3 part with two CSD17527Q5A FETs to generate 3.3V from a 24V input. We have recently had 2 of these circuits fail and have found that one or both of the FETs have…

  • RE: LM25085: LM25085

    Hi The application is small cell base station. The customer run WEBENCH for the part and got 70% efficiency at 8A,this is poor , why? He is on the schematic and need fast response other wise he chose competitor. I suggested him also to test the…

  • RE: LM25141: LM25141

    Guru, In that case your best bet would be LM3151, LM3152, or LM3153. 1. Input voltage range 6-42V, 6-33V, 6-42V 2. Output voltage : 3.3V 3. Output current : up to 12A 4. Internal pull- up on EN pin That's the closest we've got for your specs…

  • CSD19533 - Thermal pad design

    Other Parts Discussed in Thread: LM3152 Hi, I'm designing a 24V - 3.3V@2A DC/DC converter. I'm using LM3152 to control 2 CSD19533 in a synchronous buck topology. I'm using a 4 layer board. The thickness of the copper is 35 um (70um after plating) The…
