DESCRIPTION
The KK1503 is a CMOS LSI LEDs driver circuit. An automatic cut off function is built in to lower the current consumption. The metal mask can be modified in order to adjust the flashing rate, the duty cycle and the time of flash to a particular value. Besides, two output LEDs can be flashed in phase or alternative by mask...
