FEATURES
● Operating voltage range: – VCC range: 2.7 V to 5.5 V – EN, SDA, and SCL pins compatible with 1.8-V, 3.3-V, and 5-V power rails – Output maximum voltage: 6 V● 12 Constant-current sinks with high precision – 25.5 mA Maximum per channel with VCC in full range – 35 mA Maximum per channel when VCC ≥ 3.3 V – Device-to-device error: ±5%; channel-to- channel error: ±5%
● Ultra-low quiescent current: – Shutdown mode: 1 µA (maximum) with EN low – Power-saving mode: 10 µA (typical) with EN high and all LEDs off for > 30 ms
● Integrated 12-bit, 29-kHz PWM generator for each channel: – Independent color-mixing register per channel – Independent brightness-control register per RGB LED module – Optional logarithmic- or linear-scale brightness control – Integrated 3-phase PWM-shifting scheme
● 3 Programmable banks (R, G, B) for easy software control of each color
● 2 External hardware address pins allow connecting up to 4 devices
● Broadcast slave address allows configuring multiple device...
