Application Equations
Setting Output Voltage Setting Margin Control
Default output voltage: 0.591 V 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
The outut voltage may be adjusted with a resistor placed floating, the feature is disabled. The maximum margining range is
between the "Trim" and "-Sense" pin. ±33% of the oputput default voltage setting, with maximum
output at 5.5 V
The formula for calcuating the value of this resistor is:
Rmargin Rtrim + 2k
Vmargin_up = 0.1182 * *
Rtrim (kΩ) = 1.182 Rofs+ Rtrim
Vout - 0.591
Rmargin Rtrim + 2k

Default Turn-on voltage: 2.9 V (300 mV Hysteresis) Default Turn-on voltage: 4.3 V (300 mV Hysteresis)

The Turn-on voltage may be adjusted with a resistor placed The Turn-on voltage may be adjusted with a resistor placed
between the “Enable” and “Ground” pins. between the “Enable” and “Ground” pins.

The formula for calculating the value of this resistor is: The formula for calculating the value of this resistor is:

Ruvlo (kΩ) = 14.81 * 6.81 Ruvlo (kΩ) = 30.1 * 4.22

(6.81 * VTurn_on) - 18.16 (8.577 * VTurn_on) - 34.32
