  • LM5008A: LM5008A - non smooth startup

    TI Thinks Resolved
    Part Number: LM5008A Dear E2E, we are suffering non smooth startup issue. We found that it is due to Vin startup too slow because RT/SD pin is tie to Vin through resistor. so, we try to fast up Vin then Vout is more smooth startup. However, there are…

  • LM5008A: No power on output

    TI Thinks Resolved
    Part Number: LM5008A Other Parts Discussed in Thread: LM5008 Hello, I am having a problem with an LM5008A circuit. This LM5008A is powering a LD1117S50 and a LD1117S33 to have 5v and 3.3v. This is a schematic i took from the internet also with the PCB…

  • LM5008A: voltage drop on switching node

    TI Thinks Resolved
    Part Number: LM5008A all, A question about LM5008A switching waveform, there is a voltage drop on switching node on LM5008A EVM if Vin is 54V. If Vin is 36V, the waveform looks good, no voltage drop. Why is there a drop here? CH1 (yellow): LM5008A switching…

  • LM5008A - Need information on SHUTDOWN Current mentioned in datasheet

    Hey Everyone, I wanted to use LM85008 in my design, so want to understand few things, So I observed in datasheet of L M5008 that SHUTDOWN current is found to be 150uA. Is this SHUTDOWN current is through Vin Pin or through Ron/SD pin ? Please help me understand…

  • LM5018: Efficiency comparison of LM5018 and LM5008A

    TI Thinks Resolved
    Other Parts Discussed in Thread: LM5018 , LM5008A Hi, I was comparing the efficiency of LM5018 and LM5008A at an output load of 120mA. LM5018 has efficiency of ~78% and LM5008A has ~85% efficiency. Why is the efficiency of synchronous buck converter(LM5018…

  • Gain calculations and Bode plots for TPS61046 and LM5008A boards

    Other Parts Discussed in Thread: TPS61046 , LM5008A Hello TI, We cascaded TPS61046 EVM(Boost) and LM 5008A(Buck) as a power supply unit for sensor applications. After several experiments, I could figure out the values, behaviour of the components as per…
