  • LM3480: LM3480 turns off output unexcpectedly at startup

    Part Number: LM3480 Hello. When I apply voltage to the LM3480IM3-15, the output from the regulator is turned on and off a couple of times before it stays at the wanted 15V. Vin ( and also Vout from regulator) ramps from 0V to 15V for approx. 20ms. Vin…

  • LM3480: LM3480 reverse current latching

    Resolved
    Part Number: LM3480 Hi, I have a LM3480 for supplying an µC from 12V. Because I want to use the 5V supply from the progger without any 12V supply I have an inverse Schottky diode across the (between in- and output) of the LM3480. Unfortunately the…

  • LM3480: Doesn't work up to maximum rated input voltage

    TI Thinks Resolved
    Part Number: LM3480 The LM3480IM3-3.3/NOPB voltage regulator will not work in our test circuit with Vin above 16V. When Vin > 16V the output voltage begins to decrease to ~ 2.6V and current is limited to < 30mA. Ambient temperature was around…

    Part Number: AMC1306E25 Other Parts Discussed in Thread: LM3480 , TIDA-00914 Hi Ti , In the circuit diagram of TIDA-00914, when the AMC1306 is used for current sensing, an LDO(LM3480) is employed between AVDD and AGND to serve as the power source for the…

  • RE: LM3480 Failing at 24 VDC input

    Hi David, Attached is a screen-shot of the circuit I mentioned in my last post regarding the LM3480 failures. Note that I installed a 100V/1A schottky diode across Vin and Vout in case RC was the issue. Even though there could be a condition of reverse…
