Texas Instruments LP8864EVM LED Driver Evaluation Module (EVM)

Texas Instruments LP8864EVM LED Driver Evaluation Module (EVM) helps designers evaluate the characteristics, operation, and performance of the LP8864(S)-Q1. The LP8864(S)-Q1 is a 4-channel high-efficiency LED driver for automotive display LED backlighting. The Texas Instruments LP8864(S)-Q1 integrates a boost or SEPIC controller and four high-precision current sinks. The boost controller has adaptive output voltage control based on the headroom voltages of the LED current sinks. The four current sinks support phase shifting that is automatically adjusted based on the number of channels in use. LED brightness can be controlled through the I2C interface or PWM input. The product also supports extensive fault detection features.
