  • LM3478: Input resistor proper placement

    Resolved
    Part Number: LM3478 Hello team, The LM3478 datasheet states that "To improve performance, especially with Vin below 8 volts, it is recommended to use a 20 Ohm resistor at the input to provide an RC filter". That is on paragraph "8.2.1.2.8 Input…

  • LM3478: Current sense gain?

    Resolved
    Part Number: LM3478 I'm designing a boost converter with this part. Nothing fancy, just 12V to 48V with 0.5A output current. However this does push it into CMC mode that's somewhat more complex. With the "improved" webench, we no longer have…

    Part Number: LM3478 Hi, TEAM Is there any problem with the characteristics of this product even if it is operated at 100KHZ? Do you have data for this product to work at 100KHZ? Best Regards, BANE

  • LM3478: Can a capacitor be added to the SD (Shut Down) pin of the device

    Part Number: LM3478 To Whom it May Concern, We would like to stop the LM3478 from powering on at board power on. Can we add a cap to the SD pin as shown in the picture attached to delay the LM3478 from turning on? And would this then affect the frequency…
