Product Overview
The LP5569 is a Texas Instruments nine-channel RGB LED driver for LED applications requiring multiple independently controlled current sinks. LED0 through LED8 support up to 25.5 mA per channel, with 8-bit current control and 12-bit internal PWM control at 20 kHz. PWM direct input dimming is supported from 100 Hz to 20 kHz.
For sequenced illumination, the device includes three programmable LED engines and SRAM program memory for up to 256 instructions. This structure supports stored lighting pattern sequences without active microcontroller control. Up to eight devices can be used in the same system with unique I2C slave addresses.
The device operates from a recommended VIN range of 2.5-5.5 V, with a recommended V1P8 input range of 1.65-1.95 V for digital circuitry. It is supplied in a 24-pin WQFN RTW package with a 4.00 mm x 4.00 mm body and exposed thermal pad. Thermal data includes 35.8 °C/W junction-to-ambient resistance and 4.6 °C/W junction-to-case bottom resistance.
