2. Droop & DAC Offset Setting
For each channel the load current is 100A / 4 = 25A and DCR is 0.9 m ? max at 25°C with temperature
coefficient of copper is 3900 ppm/°C.
Assume that the copper temperature is 90°C at 100A output current. The DCR at 100A should be 0.9
m ? x ( 1+ ( 90-25 ) x ( 3900 / 1000000 ) ) = 1.12815 m ? Max
Using the following formula to select the I X(MAX)
I L ×DCR
I X =
R CSN
≤
90 uA for GM amplifier :
= ? R IMAX =23.54k ? , so 24k ? choosen
Select R CSN = 330 ? , then I X(MAX) would be 85.47 uA. V DROOP = 100 mV = 85.47 uA X 2 X 4 X R ADJ ,
therefore R ADJ = 146.25 ? . Select R ADJ = 110 ? + 47 ? NTC resistor.
3. Over Current Protection Setting
OCP trip point is set by external resistor at IMAX pin. As above selected R CSN 330 ? , the OCP trip point
is found using :
1 1,6V 1 I L × DCR
2 R IMAX 3 R CSN
4. Soft-start Capacitor Selection
C SS = 100 nF is the suitable value for most application.
I SS × t SS = V SS × C SS ? C SS =
I SS × t SS
V SS
I SS = 13 uA , V SS = 2V , t SS = 10 mS
C SS = 65 nF
