Other Parts Discussed in Thread: LM3406
Hello Team,
I use the LM3406HV for dimming a LED CHain of 12 High Power LEDs. The Input Voltage is DC48V.
When I connect the VIN Pin to the Power Supply, the LEDs lights at full power. After Power On Time the LEDs are OFF and the I can DIM the Brightness.
My Problem, the LEDs must be OFF at Start Up. When I turn ON the Application the LEDs must be out. When the Controller is working then the LEDs can be dimmed to maximum.
So how can I solve the Problem? Can anybody help me?
Maybe is there an another Chip with VIN to 75V?
