3 / 4 page LGA C Series Data Sheet Application Equations 5-8 9-10 21 1-4 14 LGA C Series Enable On/Off Vin GND Rtrim Cin R L O A D Vout Cout 24 15 12 13 Rmargin +Sense -Sense Ruvlo Margin Control 23 Rofs- Rofs+ 22 Power Good GND Setting Margin Control Setting Output Voltage Setting Under Voltage Lock Out – 20 A Models Setting Under Voltage Lock Out – 3, 6, 10 A Models 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 Vmargin_up = 0.1182 * Rmargin * Rtrim + 2k Rofs+ Rtrim Vmargin_down = 0.1182 * Rmargin * Rtrim + 2k Rofs- Rtrim 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 See Technical Reference Note for other trimming methods. 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 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 *ONLY USE WITH OPEN COLLECTOR DEVICE *DO NOT DRIVE PIN WITH A VOLTAGE Notes: 1. Measured as per recommended minimum system capacitance. 2. di/dt = 10 A/ µs,12 Vin = Norm, Tc = 25 °C, load change = 50% lo 100% Imax. 3. Internal input capacitance is rated 16 Vdc maximum. External input fusing is recommended. |
