  • TPS92641: LED Voltag overshoot when PWM turns on

    Resolved
    Part Number: TPS92641 Hi, we have an issue with a TPS92641 design where the voltage on the LED significantly overshoots when the external PWM FET opens and turns on the light. Our schematic is pretty much standard. We chose quite a big inductor in order…

  • RE: TPS92641: Spec Question Asking

    Hi Jason, TPS92641 is a controller, which means two external MOSFETs are necessary to achieve BUCK topology. So the output voltage range is related with MOSFET. But the TPS92641 has requirement to input voltage and it should be lower than 85V. Since you…

  • TPS92641: TPS92641 Output Current Accuracy Question

    TI Thinks Resolved
    Part Number: TPS92641 Hi Support team I want to know how to calculate output current accuracy when I choose input voltage control (analog dimming with voltage input)?

  • TPS92641: QHS selection

    TI Thinks Resolved
    Part Number: TPS92641 Hi, I am using the TPS92641, because of sourcing problems I tried to use it with Qhs Nexperia PN PSMN004-60B,118 . Unfortunately, this part did not work. Since this part appears to be within the required design parameters (Vin=48V,…

  • TPS92641: Spec Question Asking

    TI Thinks Resolved
    Part Number: TPS92641 Hi team, I have some question would like to ask. 1.) If the average inductor current is well-regulated at 0A which meant the output is also 0A. I do not understand in this situation why we can measure the voltage and current ripple…

  • TPS92641: Does not oscillate

    Part Number: TPS92641 I designed the circuit with the recommended circuit configuration, but it does not oscillate constantly because the constant is a problem. I don't know if the range of constants is a problem or if there are parts with fixed values…

  • TPS92641: Does not oscillate

    Part Number: TPS92641 推奨回路の構成で回路設計したが、定数が問題なのか定常発振しない。 定数の取り得る範囲が問題なのか、決まった値の部品があるののかが分からない。 電流は20A流したいので定数は小さい値が多い。 電流制御はアナログ調光(IADJ)で設計している。 何処が問題か分かりませんか。

  • TPS92641: Is there any noise immunity feature on UDIM pin?

    TI Thinks Resolved
    Part Number: TPS92641 Hi, My customer found that there is noise on UDIM pin and it may trigger UDIM randomly. Is there any noise immunity feature on UDIM pin? BR, frank

  • TPS92641: sometimes, TPS92641 cannot power up

    TI Thinks Resolved
    Part Number: TPS92641 Hi, My customer use TPS92641 to drive TEC cooler. sometimes, TPS92641 cannot power up. I found that the issue may be due to Vcc is not ready and trigger UVLO. Test Conduction : Vin 52V Load : Resistor 3ohm I out : 1.37A ch1:IC…
