  • LMR16030: noise ？

    TI Thinks Resolved
    Part Number: LMR16030 hi teams: 12V IN 5V_ There is an inductive noise during the output process of out 0.3A-0.6A Inductive saturation current 3.8A. Help point out how to modify to solve the noise problem？

  • RE: LMR16030: simulation modelling of the LMR16030

    Hi Zhonghui / Elena, Thank you for your assistance with the above while my access to e2e was being resolved. I have partially resolved the simulation duration issues - the LMR16030 model in PSPICE does work, however it is much slower than LTSpice - 6 mins…

  • LMR16030: LMR16030 EMI / Design issues？

    TI Thinks Resolved
    Part Number: LMR16030 The designed DCDC circuit is as follows: 1. Input voltage range: 9v-36v; 13.8V (12V vehicle), 27.6v (24V vehicle); 2. Output: maximum 3A/5V; C244, c210: solid-liquid hybrid capacitor, ESR:30m Ω @100khz; Ripple current: 1100mA@125…

  • LMR16030: Output is 400mV decaying over time to around 340mV.

    Resolved
    Part Number: LMR16030 I've tried using this IC to design 50->12V and 50->5V regulators, but have the same unexpectedly low output from both of them. Rather than the expected voltage, around 400mV is being generated, which gradually decays to 340mV then…

  • RE: LMR16030: "LMR14050 / LMR16030" with higher input voltage ratings?

    Hello, Here's what I got back from the engineer: It can operate at close to 100% duty cycle per the datasheet. The output will drop by RDS*Iout, during dropout operation. At no load, it can become problematic due to DCM ring eating into boot refresh…

  • RE: LMR16030: design support

    Resolved
    Elena, FYI. The problem I was having was caused by the output being greater than 7V and I didn't remove the pull-up resistor on the PGOOD pin.

  • LMR16030: Efficiency at 1MHz and 2 MHz

    TI Thinks Resolved
    Part Number: LMR16030 Hi Team, Our customer is using LMR16030 regulator to convert 48V TO 3.3V. Initially they used 500KHz as switching frequency. Now they are changing the switching frequency to 1MHz and 2 MHz. He would like to know how much does it affect…

  • LMR16030: EMI filter

    Resolved
    Part Number: LMR16030 Hi, Regarding the application notes SNVA755 and SNVA489C, I have designed an input filter but i am not sure about component values. As you can see below, like in the SNVCA489C, i did not use an damping electrolytic capacitor and…

  • LMR16030: Replacing LMR16030PDDAR and LMR16030SDDAR

    Resolved
    Part Number: LMR16030 Hi support team, Can the PGOOD pin of LMR16030PDDAR be floating? Can the SS pin of LMR16030SDDAR be a floating? If both of the above are possible, is it possible to replace LMR16030PDDAR and LMR16030SDDAR? Even if the SS of LMR16030SDDAR…
