  • RE: LM3429: PSPICE for TI built-in library model appears to have problems

    I looked carefully at your simulation traces, and realized that the model started working at about 27 milliseconds. Based my experience with the LM3409 model, I was only simulating to 200 microseconds and getting activity from essentially time=zero (and…

  • LM3429: Doesn't start again after reducing input voltage

    Resolved
    Part Number: LM3429 Greetings, I'm having a difficult time with LM3429 as a driver IC. It's supposed to work properly between 9 to 16 V, and it does. Except when I lower the voltage to below 6 V, since when the circuit first turns off, it doesn't turn…

  • LM3429: efficiency 80% and low on frequency more than 300khz

    TI Thinks Resolved
    Part Number: LM3429 I have I problem with over temperature LM3429 and switching MOSFET and system work with efficiency above 80%. Maximal efficiency is only on 300khz (Rt=82k) on more high frequency, efficiency is very low. Topology: buck-boost Vin: …

  • LM3429-Q1: Automotive IC

    TI Thinks Resolved
    Part Number: LM3429-Q1 Other Parts Discussed in Thread: LM3429 , Hi, Is there any difference in the design or assembly line between the ICs LM3429-Q1 and LM3429 (non-automotive)? Both PNs have the same datasheet. Is the difference just the AEC qualification…

  • LM3429: LED driver make a lot of noise on FM-radio

    Resolved
    Part Number: LM3429 Hi Team, I've made a LED buck-boost (BB) driver based on LM3429. It's for automotive lighting, so Vin = 9-14.5 V, LED string consist of 10 white leds. Vout is about 30V, Iout=1.3A. All components were calculated according to LM3429…
