Application Equations
Setting Output Voltage
Default output voltage: 0.591 V
The outut voltage may be adjusted with a resistor placed between the
"Trim" and "-Sense" pin.
The formula for calcuating the value of this resistor is:
1.182
Rtrim(kΩ) =
Vout - 0.591
See Technical Reference Note for other trimming methods.

Setting Under Voltage Lock Out - 3, 6, 10 A Models
Default Turn-on voltage: 2.9 V (300 mV Hysteresis)
The Turn-on voltage may be adjusted with a resistor placed
between the "Enable" and "Ground" pins.
The formula for calculating the value of this resistor is:
14.81 * 6.81
Ruvlo(kΩ) =
(6.81 * VTurn_on) - 18.16
*ONLY USE WITH OPEN COLLECTOR DEVICE
*DO NOT DRIVE PIN WITH A VOLTAGE
GND
-Sense GND
External input fusing is recommended.
Setting Under Voltage Lock Out - 15 and 20 A Models
Default Turn-on voltage: 4.3 V (300 mV Hysteresis)
The Turn-on voltage may be adjusted with a resistor placed between
the "Enable" and "Ground" pins.
The formula for calculating the value of this resistor is:
Ruvlo(kΩ) = 30.1 * 4.22
(8.577 * VTurn_on) - 34.32
*ONLY USE WITH OPEN COLLECTOR DEVICE
*DO NOT DRIVE PIN WITH A VOLTAGE
Setting Margin Control
To margin the output up, pull the margin control pin high. To margin
down, pull the margin control pin low. If the pin is left floating, the
feature is disabled. The maximum margining range is ±33% of the
oputput default voltage setting, with maximum output at 5.5 V
