Frequent questions

  • [FAQ] TPS54824: What is the startup process in terms of FB, SS/TRK and COMP pins?

    Part Number: TPS54824 The device has been designed to prevent the low-side MOSFET from discharging a pre-biased output. During monotonic pre-biased startup, the low-side MOSFET is not allowed to sink current until the SS/TRK pin voltage is higher than…

  • [FAQ] TPS54A24: How to reduce noise at Vin, Vout and when taking measurements?

    Part Number: TPS54A24 Noise reduction for VIN and VOUT There are things which can be done to reduce this noise such as adding a boot resistor or snubber, adding input or output caps for high frequency bypass or adding some inductive filtering. Noise…

  • [FAQ] LM5141: loop compensation

    Part Number: LM5141 Hi there, about LM5141 test, I have some questions. 1. Equation(60) shows calculating Rcomp, how this equation comes from? any more detialed deduction? 2.when inductor is too large, loop instability occurs. You said it's because…
