  • RE: LMR54406: Can't get the specified current value with LMR54406

    Dear Mr Noguchi, For the TPS62824 and the conditions you mentioned, the total power dissipation is around 80.3mW. Around 64.5mW of this is from IC and the rest from the inductor. You can use our tool WEBENCH Power designer tool for getting a lot of useful…

  • LMR54406: FRA while working in the current limit mode.

    Part Number: LMR54406 Hello! Introdution I have a buck converter which have to charge battery so it works in current limit mode. Instead of using internal current limiting feature I use external ciruit which consist of: 1) differential amplifier which is…

  • LMR54406: Is this a CMOS-only DC/DC converter? (If not, are there any fully integrated and/or buck controller ICs that are?)

    Resolved
    Part Number: LMR54406 I was looking for DC/DC converters (drivers, or fully integrated converters) that do not utilize BJTs in the internal design structure. For my application, I'm looking for ICs that are completely constructed from CMOS circuitry…

  • LMR54406: parasitic capacitance and inductance value

    Part Number: LMR54406 Hi team, My customer is using LMR54406 (Buck Converter). And they tested a -1.8V negative voltage at SW pin when the high side MOS closed. And it last about about 60ns from -1.8V to 0. The test method is as recommended. So I think…

  • RE: LMR14010A: soft start time or etc

    Resolved
    Hi Kota 5V is your output voltage, right? What is your Vin range? What is the load? The soft start time (tss) of LMR54406 is not specified in datasheet, but seen from the Figure8. Start up waveform, the tss should be around 0.8ms. Since LMR54406 is non…

  • TPS7A20: TPS7A2033

    TI Thinks Resolved
    Part Number: TPS7A20 Other Parts Discussed in Thread: LMR54406 I designed with TPS7A2033 and it doesn't work. However, it can work normally with a regulated power supply of 100mA. I don't know why?
