  • WEBENCH® Tools/LMZ10503: LMZ10503 WEBENCH Designer

    TI Thinks Resolved
    Part Number: LMZ10503 Tool/software: WEBENCH® Design Tools Hi, I tried to use TI WEBENCH Designer to design a circuit using LMZ10503 with the following specs: Input voltage range 3V to 5.5V Output voltage range 4.5V to 5V Output current 2A or 3A Ambient…

  • LMZ10503: Impedance variation after a term of usage

    Part Number: LMZ10503 Hi, We have used LMZ10503 in our one of the design with Artix-7 FPGA. This is used for core voltage(1.0V) supply for the FPGA. We have about 100 boards with us. We have observed that the initial impedance of the voltage net with…

  • WEBENCH® Tools/LMZ10503: Webench design re-comp and sim difference

    TI Thinks Resolved
    Part Number: LMZ10503 Tool/software: WEBENCH® Design Tools Hello, I'm using Webench designer to simulate a simple circuit using LMZ10503 part. If I simulate my circuit with the SIM tab and show the bode plot, my design seems to be unstable (10…

  • massive failure of the LMZ10503

    Other Parts Discussed in Thread: LMZ10503 Hello. We use LMZ10503 chip in our devices. In the last series we originated a massive failure of the chip. It is a short circuit between input, output and ground. The most common fault occurs at a temperature…

  • LMZ10503

    Hi EOS Issue occured and observed short mode between Vin , Vout and GND in my customer condition. And our customer observed some devices is going lower impedance between Vout and GND in operation mode than the others. We got waveform at startup. Please…

  • Verification needed on WEBENCH Designer solution for LMZ10503

    Other Parts Discussed in Thread: LMZ10503 Hi, I used the WEBENCH Designer to find a buck converter regulating a voltage in of 3.4 to 3.6V, with a desired regulated voltage out of 3.3V and 0.3A. Actually I wasn't expecting it to find anything, as I understand…
