・The above values are fixed numbers for confirmed operation with the following conditions: V
CC
= 12V, four parallel channels
of five series-connected LEDs, and ILED=50mA.
・Optimal values of external components depend on the actual application; these values should only be used as guidelines
and should be adjusted to fit the operating conditions of the actual application.
When performing open/short tests of the external components, the open condition of D1 or D2 may cause permanent
damage to the driver and/or the external components. In order to prevent this, we recommend having parallel connections
for D1 and D2.
