12 V/7.5 A Typical Characteristics
Start-up
Start-up enabled by connecting VI at:
Tref = +25°C, VI = 53 V,
IO = 7.5 A resistive load.
Output Ripple & Noise
Output voltage ripple at:
Tref = +25°C, VI = 53 V,
Io = 7.5 A resistive load.
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:
Example: Increase 2% =>Vout = 12.24 Vdc
Output Voltage Adjust Downwards, Decrease:
Example: Decrease 4% =>V

Shut-down
Shut-down enabled by disconnecting VI at:
Tref = +25°C, VI = 53 V,
Io =7.5A resistive load.
Output Load Transient Response
Output voltage response to load current step-
change 1.875A-5.625A-1.875A at:
Tref =+25°C, VI = 53 V.
Active adjust
The output voltage may be adjusted using a {current/voltage} applied to the
Vadj pin. This {current/voltage} is calculated by using the following equations:
Example: Upwards => 12.50 V
Example: Downwards => 11.50 V
