Turn 12 3V 1A LEDs on or off using an IC

Other Parts Discussed in Thread: TPIC6A595, CSD13383F4, TPL7407LA, SN74HCS238, SN74HCS164, TPS92200

Hey there!

I'm looking for an IC that I provide with 3V 1A power and some kind of signal (from my Raspberry Pi) and it outputs that 3V 1A to one of 12 (can be lower and use multiple) LEDs to turn them on. What part is right for me? LEDs used:


  • With TPIC6A595‍s, you would require three outputs in parallel per LED to reach 1 A, and a level shifter to get 5 V input signals.

    You can use separate drivers, e.g., four TPL7407LA‍s with two outputs in parallel per LED. Alternatively, use one discrete MOSFET (e.g., CSD13383F4) per LED.
    If you want fewer than eight control signals, use a decoder (e.g., SN74HCS238) or shift register (e.g., SN74HCS164).

    And how are you regulating the current for these LEDs?

  • i recommend you to use TPS92200 in this case
