1 Features
? Operating voltage range:
– VCC range: 2.7V to 5.5V
– EN, SDA, and SCL pins compatible with
1.8V, 3.3V, and 5V power rails
– Output maximum voltage: 6V
? 24 constant-current sinks with high precision
– 25.5mA maximum per channel with VCC in full
range
– 35mA maximum per channel when VCC ≥ 3.3V
– Device-to-device error: ±7%; channel-tochannel
error: ±7%
? Ultralow quiescent current:
– Shutdown mode: 1μA (maximum) with EN low
– Power saving mode: 10μA (typical) with EN
high and all LEDs off for > 30ms
? Integrated 12-bit, 29kHz 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 devices simultaneously
? Auto-increment allows writing or reading
consecutive registers within one transmission
? Up to 400kHz fast-mode I2C speed
2 Applications

? STB and DVR
? Smart router
? Handheld device
3 Description
In smart homes and other applications that use
human-machine-interaction, high-performance RGB
LED drivers are required. LED animation effects
such as flashing, breathing, and chasing greatly
improve user experience, and minimal system noise
is essential.
The LP50xx device is an 18- or 24-channel constant
current sink LED driver. The LP50xx device includes
integrated color mixing and brightness control,
and pre-configuration simplifies the software coding
process. Integrated 12-bit, 29kHz PWM generators for
each channel enable smooth, vivid color for LEDs,
and eliminate audible noise.
