  • LM5165: Output Overvoltage

    TI Thinks Resolved
    Part Number: LM5165 Tool/software: Hello, Please can you confirm LM5165's behavior during output overvoltage fault i.e. when external overvoltage is applied on Vout pin. My understanding is that as LM5165 prevents negative inductor current, the IC…

  • LM5165: Behaviour when Input Current Limit is reached

    TI Thinks Resolved
    Part Number: LM5165 Tool/software: Hello, I set Input current limit as 180mA typical through ILIM pin. Please help to answer below - During startup condition, if the Input current reaches this limit. Will LM5165 be prevented from starting up ? or Will…

  • RE: TIDA-00666: LM5165

    Resolved
    Thank Juergen for your kind explanation. Now the challenge is how to get VIN_DCDC? it sounds this VIN_DCDC is varied if the ILOOP current is varied from 4mA to 20mA. Assuming this VIN_DCDC is varied (referred to GND), the VOUT_DCDC is stable and fixed…

  • LM5165: Input voltage dips less than Output voltage when Large Output Bulk Cap

    TI Thinks Resolved
    Part Number: LM5165 Tool/software: Hello, In my application, Output setpoint is 3V3 but the Vin dips to 2.8V for 200us. Due to large bulk output cap, the Vout will be higher than Vin during that dip duration. The enable pin is tied to Vin. My understanding…
