Texas Instruments LP8870Q1EVM Evaluation Module
Texas Instruments LP8870Q1EVM Evaluation Module is a platform for evaluating the performance of the LP8870-Q1 high-efficiency LED driver with boost controller. The six 150mA high-precision current sinks enable phase shifting that is automatically adjusted according to the number of channels in use. The TI LP8870Q1EVM LED brightness can be controlled globally via the I²C interface or PWM input.
