  • [FAQ] End of life (applies to ALL TI devices)

    Other Parts Discussed in Thread: LMG1210 Hi, I want to use the LMG1210 for a new design, but I want to make sure that I can manufacture the part for a few years to come. My question is when was the LMG1210 released and when will it reach it's end-of…

  • [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…
