Applications Fun and Indicator Lights LCD Sub-Display Backlighting Keypad RGB Backlighting and Phone Cosmetics Vibra, Speakers, Waveform Generator Blood Glucose Meter Handheld POS Terminals Electronic Access Control Where RGB Indicationis Needed
Typical Application Circuitcharge pump gain based on LED forward voltage
requirements and is able to automatically enter
power-save mode, when LED outputs are not active
and thus lowering current consumption.
Three independent LED channels have accurate
programmable current sources and PWM control.
