  • LM5116: LM5116

    TI Thinks Resolved
    Part Number: LM5116 Good morning Can you please thell me the difference between the LM5116MH and the WG version, (apart from a £130 price difference, and a different package). The data sheet states that the WG regulator is for "harsh" environments…

  • RE: LM5116: pls help reiew schematic diagram designing of LM5116 and give same suggest?

    The switching freq is 200KHz. MOSFET Qg is 48nC, Qgs=15nC HS and LS driving current is (15+48)nCx200KHz=12.6mA Iq is 5mA LM5116 power loss 24Vx+(5+12.6)=422mW Theta_JA is 40C/W, then temp increase is 40x0.422=17C. so the IC should not be hot than 42C…

  • LM5116: LM5116 low side Gate drive failed

    TI Thinks Resolved
    Part Number: LM5116 Hi TI Experts, I designed a DC-DC converter using LM5116 with output voltage 13.5V. I started testing the board with the LM5116 EVM Values. board worked well with 30V input and loaded up to 4A successfully. When i applied 50V input…

  • LM5116: LM5116-12EVAL inductor value not correct ?

    Resolved
    Part Number: LM5116 The LM5116-12EVAL board uses a 10uH inductor. i used the formula in the LM5116 datasheet (page 23) and used these values: VinMAX = 80V Vout = 12V Ipp = 2A fsw = 250000 Hz The result is around 20uH 10uH would result in around 4A of…
