1 Introduction
The LP8864EVM helps designers to evaluate the characteristics, operation, and use of the LP8864-Q1 device, a
high-performance LED driver for automotive lighting. The LP8864-Q1 device is a high-efficiency LED driver with
boost controller. The four 200-mA high-precision current sinks support phase shifting that is automatically
adjusted based on the number of channels in use. LED brightness can be controlled globally through the I2C
interface or PWM input.
