  • LM5116: Lm5116

    Part Number: LM5116 Tool/software: Hi Team, I am using lm5116 in my design for DC DC converter. Input voltage is 72 V and output is voltage is 12. When I am connecting load 3A output voltage is dropping and ic is heating up. Can you please help increase…

  • LM5116: LM5116 as current limiting IC, working and logic as how it limits the current.

    Part Number: LM5116 Tool/software: Hi Everyone, We need to know how this LM5116 is limiting the current? How does this IC triggers and protect the circuit when the current between Vin and Vout is reached to its specific current limit? It should limit…

  • LM5116: Voltage Drops Under Load on LM5116-Based 60V to 6.5V Regulator

    TI Thinks Resolved
    Part Number: LM5116 Tool/software: Hello, I recently built a 60V to 6.5V DC-DC buck converter based on a design generated by the TI Webench tool. The design uses the LM5116MH/NOPB regulator IC. The regulator seems to work fine when there is no load,…
