  • LM3150: Frequency calculation / inconsistent K

    Resolved
    Part Number: LM3150 Other Parts Discussed in Thread: LM25145 , LM25117 Hello, We want to use the LM3150 to buck down 19V to 5V, with Iout peak of 10A, but we can't figure out the switching frequency and current limit by the equation provided in datasheet…

  • LM3150: Voltage intermittently slightly high. FB node reflects this.

    TI Thinks Resolved
    Part Number: LM3150 Conditions: VIN: 7.5-15V Vo = 3.738V(I have no idea why?) Io = 3.25A The problem is we have been seeing a small percentage of boards with this supply come in that show a voltage of ~3.9V on the output, some as high as 4V. The…

  • LM3150: LM3150 not regulating

    Resolved
    Part Number: LM3150 I'm trying to have a 3.3V 9A (very similar to eval board) with an air core inductor and I'm having an issue with keeping regulation, I had to remove my Cff cap in order to get the output to the proper voltage, with this cap populated…

  • LM3150: LM3150 switching between 5.5V and 7V using reference design

    TI Thinks Resolved
    Part Number: LM3150 I used the TI Power Designer and put in 12V minimum, output 5V 15A and used the LM3150 reference design. I imported it into Eagle and layed out the board and have assembled 3 of them and they all exhibit the same behavior. Measuring…

  • RE: LM3150: LM3150 stability calculations

    Resolved
    Hello Jacob, The LM3150 is a Constant on time (COT) control architecture, its an on/off control architecture and Bode plots and compensation are not used with COTs. For stable operation, we ensure the device as a ripple voltage at the feedback node…
