  • LM63635-Q1: ICs doesn't always start

    Part Number: LM63635-Q1 Hello, I use the LM63635-Q1 to convert 15V to 5V. I have a weird behaviour with a few boards. Sometimes the 5V doesn't start, no switching. 5V increases slowly to 0.985 V and stays at this value ( as if the IC if supplying the…

  • LM63635-Q1: Return issue question

    TI Thinks Resolved
    Part Number: LM63635-Q1 Hi Team, We got the return issue when using Vin = 26V. (Typ = 12V) VIN/FB/EN/Vcc short to GND. Vin-SW was also short. We did some experiments. (Let IC in normal operation and then short Vboot to SW) And then we gave Vin = 12V…
