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:
Rtrim (kΩ) =
1.182
Vout - 0.591
Vmargin_up = 0.1182 *
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

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:
Ruvlo (kΩ) =
14.81 * 6.81
(6.81 * VTurn_on) - 18.16
Setting Under Voltage Lock Out
– 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
