The LC410591FN is a power supply IC for white LEDs. It incorporates a charge pump-type DC/DC converter circuit and has four constant-current outputs. The input voltage ranges from 2.7V to 5.5V. The maximum value of the current flowing to the LEDs can be determined by the resistance value of the external resistors. The LC410591FN can supply a total current of 105mA for one to four white LEDs. A maximum current of 26mA can be supplied to one white LED when driving four LEDs, and a maximum current of 35mA can be supplied to one white LED when driving three LEDs. The IC operates at a fixed frequency of 600kHz without using an inductor, resulting in very low EMI noise. |
