  • LM5104: Wrong signal when connect to mosfet

    TI Thinks Resolved
    Part Number: LM5104 Other Parts Discussed in Thread: LM5106 , LM5105 Dear engineer： I meet a problem when using LM5104. Let me express the condition. When the pin LO is not connected to the gred of a mosfet, it's output wave is right(P1). But as soon…

  • LM5104: To work as a switch, not with PWM

    TI Thinks Resolved
    Part Number: LM5104 Hi ! I am as Rodrigo working on a prototype based on the LM5104 working as a switch. The purpose of this montage is to turn on/off a DC voltage (VCC2) going from 1,25 to 7V with a standard 3V3 logic command, knowing that it will mainly…

  • LM5104: To work as a switch, not with PWM

    TI Thinks Resolved
    Part Number: LM5104 Hi! I'm working on a prototype with LM5104, basically the datasheet recomended circuit for a halfbridge system, with some adds. It's working perfectly with a PWM input signal, but I need to modify this to work just as a switch. I…

    TI Thinks Resolved
    Part Number: LM5104 Hi, the enclose scope picture shows the output signal at OUT and with no load at all. Why this distorted rising egde? Vdd is 13.1V Why is the waveform not a direct square wave but have this slope after 10V? Supply is 13.1V t

  • LM5104: LO signal

    Resolved
    Part Number: LM5104 My input signal is 1MHz, 50% duty cycle, square wave. Output load is no load or PZT load. When OPA_HV voltage <5V, the HO and LO signal is good. But, OPA_HV voltage >5V, the LO turn on time is decrease 100ns, HO signal turn…
