    3.3 V/15 A Typical Characteristics
    PKU 4510
    Start-up
    Shut-down
    Start-up enabled by connecting V
    I at:
    Tref = +25°C, VI = 53 V,
    IO = 15 resistive load.
    Top trace: output voltage ( 1 V/div.).
    Bottom trace: input voltage ( 50 V/div.).
    Time scale: ( 2 ms/div.).
    Shut-down enabled by disconnecting V
    I at:
    Tref = +25°C, VI = 53 V,
    IO = 15 A resistive load.
    Top trace: output voltage ( 1 V/div.).
    Bottom trace: input voltage ( 50 V/div.).
    Time scale: ( 1 ms/div.).
    Output Ripple & Noise
    Output Load Transient Response
    Output voltage ripple at:
    Tref = +25°C, VI = 53 V,
    IO = 15 A resistive load.
    Trace: output voltage ( 20 mV/div.).
    Time scale: ( 2 μs/div.).
    Output voltage response to load current step-
    change (3.75 - 11.25 - 3.75 A) at:
    Tref =+25°C, VI = 53 V.
    Top trace: output voltage ( 200 mV/div.).
    Bottom trace: load current ( 5 A/div.).
    Time scale: ( 0.1 ms/div.).
    Output Voltage Adjust (see operating information)
    Passive adjust
    The resistor value for an adjusted output voltage is calculated by
    using the following equations:
    Output Voltage Adjust Upwards, Increase:

    Active adjust
    The output voltage may be adjusted using a voltage applied to the
    Vadj pin. This voltage is calculated by using the following equation:
