  • LM5046: Switching Frequency and Oscillator Frequency

    TI Thinks Resolved
    Part Number: LM5046 Other Parts Discussed in Thread: LM5035 Tool/software: Hello E2E Experts, Good day. In LM5046 and LM5035, there is no Dmax. I can't calculate the switching frequency. So these components can make up to 2MHz oscillator frequency…

  • LM5046: Cannot go minimum duty (maximum phase shift)

    Part Number: LM5046 Hi All, I have a question regarding the output of the LM5046, the datasheet says the duty can vary from 0-100% with the COMP pin varying between 1 mA to 0 mA. In my design, the switched voltage waveforms of the PSFB converter reach…

  • LM5046: UNABLE TO OBTAIN HIGH SIDE OUTPUTS

    Part Number: LM5046 Hi everyone, I am currently working with the IC LM5046MH/NOPB and trying to achieve a phase shifted full bridge operation. I am trying to generate the phase shifted PWM pulses for the switching MOSFETs. I am able to achieve the…

  • LM5046: Thermal issues with PWMs at 1 MHz!

    Part Number: LM5046 Hi All, I'm using LM5046 for a custom application which involves running the oscillator at ~2MHz (RT Resistor = 4.7K), hence the PWMs at 1 MHz. With this, I have connected the output of LM5046 (LO1/HO1, LO2/HO2) to the gate driver…
