  • LM63615-Q1: <100kohm FBT

    TI Thinks Resolved
    Part Number: LM63615-Q1 Hi team, Due to maximum resistor value restrictions for automotive design rule (avoid weak short due to water), I cannot use >100kohm resister. Can I use <100kohm resistor for FBT(feedback divider top resistor)? regards…

  • LM63615-Q1: Recommended Pi Filter Justification

    TI Thinks Resolved
    Part Number: LM63615-Q1 Hi, I've to use the Pi filter, recommended in the datasheet for buck converter with Input condition of 9V-16V to deliver an output of 5V, 1A. However I'm not able to figure out: 1) What is the purpose of the Resistor which…

  • LM63615-Q1: Input capacitance

    TI Thinks Resolved
    Part Number: LM63615-Q1 Hi team, I have a question about input capactiance for LM63615-Q1. Vout=5V, Iload max =400mA. Vin=car battery It is recommended to place at least 4.7uF as Cin in the datasheet. Is it possible to minimize it to 1uF if I have bulk…

  • LM63615-Q1: Fsw tolerance

    TI Thinks Resolved
    Part Number: LM63615-Q1 Hi team, I would like to set RT value to make minimum Fsw>1.8MHz using Spread Spectrum (+/-5% for WSON). How much is the minimum RT value I can choose? In order to make sure Fsw>1.8MHz, I would like to select the RT=6.8kohm…

  • LM63615-Q1: Transient Pulse 1B

    TI Thinks Resolved
    Part Number: LM63615-Q1 Other Parts Discussed in Thread: LMR36520 Hi, Good Day. As the customer is using the LM63615DQPWPRQ1 in our design, they are testing it for Transient Pulse 1B as per the ISO 6737-2, so the maximum voltage will have appeared across…

  • LM63615-Q1: momently drop

    TI Thinks Resolved
    Part Number: LM63615-Q1 Other Parts Discussed in Thread: LM63635-Q1 Hi team, I have a question about the behavior of LM63615-Q1 after it recovers from momently drop of supply (car battery) from normal 12V to 0V. 1. Does it recover automatically without…

  • LM63615-Q1: Converter input short failure

    Part Number: LM63615-Q1 We are using LM63615DQPWPRQ1 to supply two 12V axial fan. Converter input voltage is 24V. Total measured nominal output current for fan's is 600mA. Fan startup maximum current is 1000mA for short time period. Design done according…

  • LM63615-Q1: LM63615DQPWPRQ1 - Pulse 5b of 35V (400ms) - is sustainable? - 15 Pulse each/min.

    TI Thinks Resolved
    Part Number: LM63615-Q1 We are using LM63615DQPWPRQ1 Step Down Voltage Converter in our design as we are using the TVS Diode of rated 24V and Vbr = 26.7 and clamping of 38.9V So during the Pulse 5b - TVS remain in the Breakdown region, and it gets on …
