  • LM2576HV: Use the non-adjustable version BUCK as adjustable version to output adjustable voltage, which will cause increased quiescent current and chip heat

    TI Thinks Resolved
    Part Number: LM2576HV Issue: Customer use LM2576HVS-5.0 as the adjustable version to output adjustable voltage. When the input voltage is 48Vand the setting output voltage exceed 40V, the power dissipation of this IC is unexpectedly high, in some…

  • LM2576HV: LM2576HV - damage of the diode

    Part Number: LM2576HV I would like technical support to understand the damage of the diode in the buck regulator circuit. The circuit is converting VIN: 50V to VOUT: 5V with a current of 100mA. The diode used is PN: SB5100 of 100V / 5A. I am using this…

  • LM2576HV: Vout max is wrong in the datasheet

    TI Thinks Resolved
    Part Number: LM2576HV Hi there, a customer highlighted this, can you please tell me what is the actual number for Vout....MAX at 25C? The Red circle below. Max is lower than nominal (4.75V). Device: LM2576HVT-5.0/NOPB
