| 24602:
Hey All, Working on driving 12-24V LED strips from a TLC59711, I have attached a schematic Just need a double check of the work and confirm would the Gate voltage be ok at 5V? Need a double check if my Transistor and mosfet combination is correct. Will be driving approximately 1A of LEDs per channel Thanks! |

You can add a small gate resistor (e.g., 10Ω) in series with the MOSFET gate. It will limit the inrush current. |

What inrush current? The gate charges to turn on the MOSFET via a fricking 10K resistor! The PWM period is about 50us, (nom. 10MHz internal greyscale clock divided by 512, see datasheet: Figure 22. ES-PWM Operation) and I suspect the above gate drive circuit will be *far* too slow. Edit: confirmed by simulation. Wont work! :horse: |
