Start-up

Shut-down

Start-up enabled by connecting VI at:

Tp1 = +25°C, VI = 53 V,

IO = 50 A resistive load.

Top trace: output voltage (0.5 V/div.).

Bottom trace: input voltage (50 V/div.).

Time scale: (5 ms/div.).

Shut-down enabled by disconnecting VI at:

Tp1 = +25°C, VI = 53 V,

IO = 50 A resistive load.

Top trace: output voltage (0.5 V/div.).

Bottom trace: input voltage (50 V/div.).

Time scale: (0.1 ms/div.).

Output Ripple & Noise

Output Load Transient Response

Output voltage ripple at:

Tp1 = +25°C, VI = 53 V,

IO = 50 A resistive load.

Trace: output voltage (20mV/div.).

Time scale: (2 µs/div.).

Output voltage response to load current step-

change (25-37.5-25 A) at:

Tp1 =+25°C, VI = 53 V.

Top trace: output voltage (50mV/div.).

Bottom trace: load current (10 A/div.).

Time scale: (0.5 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:
