FAN5611 Datasheet, PDF (9/12 Pages) Fairchild Semiconductor – Low-Dropout LED Drivers for White, Blue or any Color LED

PRODUCT SPECIFICATION
– Amplitude sets maximum LED current
– Pulse width controls between 0 and maximum
- PWM - 2
Set VCONTROL and RSET for maximum LED current
I_LED ∼ 200 × I_SET
ON/OFF = PWM
– Amplitude has no effect on current
– Pulse width controls between 0 and maximum
