Using the BOOST-LP5569EVM Evaluation Module
The Texas Instruments LP5569 evaluation module (EVM) helps designers evaluate the operation and
performance of the LP5569 nine-LED driver. The LP5569 device is an RGB LED driver that can
individually control up to 9 LEDs. The driver has 12-bit PWM and 8-bit current control of each low-side
LED current sink. The current sinks can be individually controlled through the I
2
C interface.
The EVM contains one LP5569 device (see
).
