  • LM46002-Q1: Soft-Start time concern

    TI Thinks Resolved
    Part Number: LM46002-Q1 Other Parts Discussed in Thread: LM46002 Hi TI expert, May I have your help to check whether LM46002 A QPWPRQ1 has any minimum soft-start time limitation? We would like to control the SS time within 0.5ms, so it will be lower than…

  • LM46002: Enable pin won't work on inverting configuration

    TI Thinks Resolved
    Part Number: LM46002 Hello all, I'm using LM46002 to generate a negative rail and if i wire the enable pin to Vin al goes fine. If I try to handle the enable pin as described in SNVA722b application report i found that on some board the LM46002 don…

  • LM46002: Question for leakage current on each pin of LM46002

    TI Thinks Resolved
    Part Number: LM46002 The customer measured the leakage current of pins 8 and 12 of LM46002 as shown. They think it is defective because there is a slight difference compared to normal products. Can you see it as defective beyond the scope of the normal…

  • LM46002: power supply stops working after 2 month ( 3rd time )

    TI Thinks Resolved
    Part Number: LM46002 Other Parts Discussed in Thread: LM46001 Hi Support There are three threads which describe the same issue with the LM46001 / LM46002 LM46002: power supply stops working after 2 month x 2 LM46001: Failure in ability to power LDO from…

  • LM46002: LM46002PWP ouput problem while powering up

    Part Number: LM46002 Hi, the Output voltage of the LM4002 is set to +5V. But sometimes in the first 100ms after powering up the output voltage rises up to 11V. Then it slowly comes back to 5V and then it works fine. The capacitor Cff which is parallel…

  • LM46002: The Vcc pin can't reach over UVLO in room temperature

    Resolved
    Part Number: LM46002 Dear team, When customers were testing, 2 of their PCBs couldn't start up. The Vcc pin was 2.7V which just meet the UVLO of Vcc. If the LM46002 was blown by a heat air gun, the IC could start up. The schematic is as followed. …

  • LM46002: When Vin=12V, the Vcc=2.6V.When BIAS=12V, the Vcc=3.3.

    Resolved
    Part Number: LM46002 Dear team, Vin and BIAS are both input of internal LDO, why give the same 12V to Vin or BIAS, output of LDO Vcc is different? 7 out of 2 LM46002 are in this situation, they may be damaged while testing, but I want to know the theory…
