  • TAS5634: Slew rate differences between PWM a+B and PWM C+D

    TI Thinks Resolved
    Part Number: TAS5634 Hi, we observe EMI diificultys in mode 011 (2xBTL, AD modulation). Slew rate at PWM C+D is >20ns, with minimal overshoot. Disconnecting doesn't affect EMI measuremt. Slew rate at PWM A+B is <10ns, with massive overshoot. Disconnecting…

  • TAS5634: Are 4 inductors recommended for PBTL?

    Resolved
    Part Number: TAS5634 Hello, I am looking to implement a 250W RMS in to 4Ω in PBTL. In the TAS5634 data sheet the Typical PBTL config (Fig 29) shows the use of 4 inductors, one each for OUTA,B,C,D. Is this required to prevent over current issues, and…

  • RE: TAS5634: Unable to achieve output power at lower impedance load

    Resolved
    Hi Adam, Please refer to attachment for the construction and inductor's specs. Construction & Specs.xlsx "Higher load of 5 ohm requires PVDD to be lowered. With 30k ROC, PVDD in 5 ohm case should be max 53V, at 27k ROC, up to 56.5V PVDD can be used…

  • TAS5634: Wire link possible between PWM controller and PWM input amp ?

    Resolved
    Part Number: TAS5634 Other Parts Discussed in Thread: TAS3251 Hi, I'm pretty sure this is a stupid question (because of EMi and high freq...), but I dare asking. Can there be a short (10-15cm) wire connection between an audio PWM controller (like TAS5508…
