  • LM3466: Looking for RGB color mixing LED driver

    Part Number: LM3466 Tool/software: Hi, I'm looking for suitable RGB strip LED driver. Strip LED voltage = 12V 576 LEDs 70W / roll ( so, 70W / 12V = 5.83A total) Each color or each channel (For example Red) color will draw about 1.94A Do you…

  • LM3466: Can this be used with a non-ground referenced constand current source?

    Part Number: LM3466 Other Parts Discussed in Thread: LM3409 Tool/software: We are using an LT3475 constant current driver which does not directly connect the LED anode to ground for PWM control. Can I connect this "return" path to the LM3466 and still…

  • LM3466: LM3466

    Resolved
    Part Number: LM3466 I am designing a controller card using LM3466 (or any other suitable IC) to balance the current for 15 arrays of 44 LED in each array. The Forward voltage is 3.1V to 3.4V. So in total 3.4 x44= 149.6V (maximum). We are using Constant…

  • LM3466: LM3466 - thermal resistance when used with heatsink - need this value for calculations/simulations

    Resolved
    Part Number: LM3466 Hi guys, I am looking for the thermal resistance value for LM3466 (TO-220 package) when I use a heatsink. There is no such value on the specsheet, only for free air convection. Thank you all in advance

  • RE: LM3466: LM3466 internal MOSFET switching Characteristics ?

    Prithviraj, I do not think given the internal slew rate of the LM3466 that it is suitable for your application. In terms of other recommendations, our newer devices are mostly buck or boost/buck-boost type LED drivers or controllers, and TI also has…

  • LM3466: Control Signal?

    Resolved
    Part Number: LM3466 Internal Switching manual shutdown/start? Not sure if I'm missing something here, but does the LM3466 have a control signal of any kind that could be switched on and off by a microcontroller. Not at highspeed or PWM, just simple…

  • LM3466: LM3466 COMM Output

    TI Thinks Resolved
    Part Number: LM3466 Hi Team, my customer wants to daisy-chain the LM3466. Is it mandatory that LM3466 COMM output needs to be connected with other LM3466 devices? For their specific use-case that would be not ideal. Regards Andreas

  • LM3466: PWM dimming

    Resolved
    Part Number: LM3466 Can the LM3466 current balancer be used with PWM dimmable current sources? I suppose that if all the LED strings of the LM3466 lighting system are ok, even with PWM dimming the system works as expected. If one LED string in the LM3466…
