  • LP5030: LP5030 design review

    Part Number: LP5030 Other Parts Discussed in Thread: LP5018 , , LP5012 Tool/software: Hi Team, We're using LP5030, LP5018 & LP5012 in our design. 1. Can we connect the address pins to VCC or GND through a 4.7kΩ or 10kΩ resistor? 2. How is the power…

  • LP5030: differnt VLED

    TI Thinks Resolved
    Part Number: LP5030 Hi team, Is it possible to bian different VLED in different port? If they connect 2 LEDs, they want to bias 12V. If they want to use 1 LED, they want to supply 5V. Best, Shoo
