  • LM63615-Q1: Input section burned

    Part Number: LM63615-Q1 In the attached circuit input side is burned along with L100 ferrite bead on the few samples. What could be the reason for burning the parts on the input side alone? Output side of the buck regulator we are getting high impedance…

  • LM63615-Q1: LM63615-Q1 taking longer time to simulate in PSpice

    TI Thinks Resolved
    Part Number: LM63615-Q1 Hi, I'm simulating the circuit for LM63615-Q1 in PSpice for 5V output. However it is taking lot of time to simulate as, it took almost 4hours to just reach the 5V (covering around 5ms of simulation runtime). Can you guys please…

  • LM63615-Q1: Is it okay to use a resistor constant other than 100 kΩ for feedback?(LM63615 and LM63625)

    Resolved
    Part Number: LM63615-Q1 Hi support team, According to the data sheet, "100 kohm is recommended for the feed back resistor constant (FBT) that determines Vout." However, we want to use a resistor of 100 kΩ or less. What is the range of resistance…

  • LM63615-Q1: Vcc bypass capacitor

    Resolved
    Part Number: LM63615-Q1 Hi team, Could you advise if 10V rated MLCC capacitor (1uF) is used as VCC bypass capacitor for LM63615-Q1? It is specified in the datasheet to use 1uF, 16V rated ceramic capacitor. The pin is rated for 5.5V max, so I would like…

  • 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: 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…
