  • TLVM13630: Fsw selection

    TI Thinks Resolved
    Part Number: TLVM13630 Hi Team, one question regarding TLVM13630 and Fsw selection. We will generate 5V with TLVM13630 from 24V. The table 7.1 recommends to use 1MHz Fsw, do you see any problem to use 531kHz for improved efficiency ? Is there a equation…

  • TLVM13630: CISPR32 conducted and radiated emission

    TI Thinks Resolved
    Part Number: TLVM13630 Hi Team, 1) Figure 8-17 and 8-18, what does it mean w/ ferrites ? Did you use ferrite bead while preforming measurements, if yes where and what kind ? 2) did you also test TLVM13630 for CISPR32 conducted emission to 30MHz ? Best…

  • TLVM13630: Question about the PGND on bottom

    TI Thinks Resolved
    Part Number: TLVM13630 Hi, I'd like to know the reason why the PGND on the bottom(28 and 29) of TLV13630 package are separated. Are there some advantages for mounting , soldering , or something? Thanks, Go

  • TLVM13630: How effective for EMI reduction the line-symmetric input is

    Resolved
    Part Number: TLVM13630 Hi, TLVM13630 has line-symmetric input-PGND pin layout, I think it will be able to contribute for EMI reduction by canceling the magnetic field by input current of each inputs. Do you have any EMI data compared with using line-symmetric…

  • TLVM13630: Soft Start

    Resolved
    Part Number: TLVM13630 Hi team, Let me make sure soft start time of TLVM13630. As for tss, does it mean EN high(start switching) to 90% settling of Vref takes 3.5ms~7ms?(Not time of EN high to start switching)? I'm not sure what tss2 means. Could you…

  • TLVM13630: SW pin/Cout

    Resolved
    Part Number: TLVM13630 Hi team, Let me double check some items. SW pin must be floating, right? When 5Vout is used, effective 25uF(min) is recommended according to table7-1. But my customer would like to use smaller output capacitance such as <20uF…

  • TLVM13630: 3.3V VLDOIN

    Resolved
    Part Number: TLVM13630 Dear *, we use TLVM13630 in configuration that outputs 3.3V is it possible to supply the VLDOIN pin 22 with 3.3V from Vout ? Do you recommend to put a 1uF 25V x7r 0603 cap on the VLDOIN pin in this case, or is a 100nF 16V x7r 0402…

  • RE: TLVM13630: auto-Shutdown of TLVM13630 at Voltages above 30V

    Resolved
    Hi Arief, I changed C23 and C24 to GRM32ER71A476ME15L, which is about 66uF at 4V but it did not fix the problem (with C31 and C32 still being 4.7u). I also tried to add 4 of the 47uF Caps and it is still this behavior at the same voltage of Vin. Also…

  • TLVM13630: PTLVM13630 vs TLVM13630?

    TI Thinks Resolved
    Part Number: TLVM13630 Team, I assume that the both PTLVM13630 (Engineering samples) and (TLVM13630) RTM devices are based on the same silicon. Correct? The main difference between the two would be that only RTM device is tested against the latest datasheet…
