  • LM2734: Boost to SW voltage

    TI Thinks Resolved
    Part Number: LM2734 Hello team, My customer in using LM2734Y in their design(12Vin, 5Vout, 0.6A) and evaluated the device operation. They found voltage between BOOST and SW is about 7V for 1ms during power-up and exceeds absolute max rating which is 6V…

  • RE: LM2734: Schottky failure around LM2734XMK

    Hello Jean-Baptiste, Happy New Year! I looked over this thread and as you mentioned, fortunately, we have a pin-to-pin compatibility. The device covers all of the specs required (as informed) with max output current of 1-A, so there shouldn't be any…

  • LM2734: Big overshot voltage of LM2734 at start-up

    Part Number: LM2734 Hi all, We found that there is big overshot voltage of LMH2734 at start-up in both Vin (5V) and Vout (3.3V) for about 10V. We have Cff=1nF, Cin=10uF, Cout=2*10uF. What the issue may it be and what we can attempt? Thanks.

  • LM2734: Tolerance

    Resolved
    Part Number: LM2734 Hi TI Team, For the LM2734 Vfb voltage, as you can see, the Vfb reference is from 0.784V to 0.816V If Tj from -40degC to 125degC. I believe that this tolerance (0.784V ~0.816V) includes initial tolerance and temperature variation. …
