( - ) : Output OFF
(H) : Constant voltage output is 2.5 time the VC pin applied voltage.
(L)
: Constant current output is (IC pin applied voltage
÷RFG resistor current).
Note : When the current flows from OUT1 to OUT2, easy constant current output function is ON.
The output current is controlled by the resistance value connected between the ILM pin and GND.
