0.75V
LED driving current is able to control by CONT input voltage. The relation between V_CONT and ILED is
ILED[A] = 0.04 * CONT[V]. If V_CONT is over the limit value, the LED current limiter turns on to keep
ILED at a constant limit current. By the CONT input hysteresis, V_CONT-ILED relation has a
area at limiter turning off.
