SP7611A/7612/7614 Low Dropout LED Driver for Any Color LED

APPLICATION INFORMATION

- Analog

Set VCONTROL and RSET for LED current

-ILED = 200 x (VCONTROL - VCTRL) / RSET

-Amplitude sets maximum LED current

-Pulse width controls between 0 and maximum

- PWM -2

- PWM -1

Set VCONTROL and RSET for LED current

ILED ~ 200 x ISET

ON/OFF = PWM

-Amplitude has no effect on current

-Pulse width controls between 0 and maximum
