Connector choice and current-carrying capacity of wire I'm fiddling around with a LED controller design - fairly typical. It will use a TI tlc5926 LED driver (nice family) which provides a constant-current sink for each of 16... |

Smallest FET for high-side LED power control For controlling power to a LED string on the high side, one can use a P-ch fet. Pull the gate to GND, and it turns ON, powering the LEDs. Pull the gate to VCC and it turns off... |

Methods for controlling LEDs Hi All - I'm looking at a project that will require control over at least 15 bi-color LEDs, common anode type probably. For flexibility, they will be treated as two sets of 15... |

Need a 1-wire type protocol Hi All - I need to control 9 bi-color LEDs as cheaply as possible. Actually, 9 groups of 9 bi-color LEDs, 81 total, but it should be a lot easier to handle them 9 at a time. I've... |
