com FAN5610 LED Driver for White, Blue or any Color LED Features • LED Driver for 4 Parallel-connected LEDs • Low Voltage Drop (<350mV) to Support Direct Li-ion Applications with Low VF LEDs • Independent Control Loop for Each LED • Regulated, Matched Constant Current in LEDs • No External Components • No EMI, No Switching Noise • Built-in DAC for Digital and PWM Brightness Control • Up to 91% Maximum Efficiency • Up to 84mA (21mA/LED) Bias Current • 2.
7V to 5.
5V Input Voltage Range • ICC < 1µA in Shutdown Mode • 3mmX3mm MLP-8 Package Description The FAN5610 generates matched current source drives for a maximum of four LEDs.
Since each LED current source has its own self-regulating loop, precise current matching is maintained even if there is a substantial forward voltage spread among the LEDs.
LED pre-selection therefore is not required.
In order to minimize voltage drop, and maximize efficiency, the value of the internal current sense resistors connected in series w...
