    TI Thinks Resolved
    Part Number: LM2623 Other Parts Discussed in Thread: LMR61428 Hello I want too use LMR61428 as an alternate for LM2623. I have found out that the only difference between these parts is the junction to ambient temperature for LM2623 is is 152.5C/W & for…

  • LMR61428: 7 - 12Vin, 13.2Vout - What max current?

    TI Thinks Resolved
    Part Number: LMR61428 Other Parts Discussed in Thread: LMR62014 I have an operating issue that is not covered by the datasheet. I have a variable 7 to 12V in and needs 13.2V out. What current can I expect out? The LMR61428 should be rated for 2.8A, but…

  • RE: LMR61428: Lmr61428 boot strap issue

    Looks like your PCB will pass a DRC for netlist connectivity but attempting a SMPS design with a single sided approach is a challenge as you are finding. The ground paths from IC pins 1 and 5 to the input and output capacitors must have the highest priority…
