Jumper S11 ILIM2 (connect ILIM2 pin to S11)
Position
OUT2 regulation
External
resistor
The threshold voltage of ILIM2 is compared with 1/10th of the GND-PHASE2 drop
during the off time to determine a valley current limit.
VREF2
The internal threshold voltage of the current limit comparator is set to 200 mV.
