The LED controller (inverter) is recommended to be used when replacing CCFL lamps with LED strips in monitors, TVs, laptops.

Key Features:

  • Input voltage: +10 ... 30 V
  • Output voltage:+9V
  • Logic level voltages ENA and DIMM: 0 ...+5 V
  • Dimensions: 7 x 2 cm
  • Connector pinout: VCC, VCC, ENA, DIM, GND, GND
  • Driver IC: DF6113
  • Connection diagram: ENA+DIMM inverted analog dimming (see datasheet for microcircuit)


Typical driver circuit:



To connect to constant full brightness, the ENA contact (enable) must have a high logic level (+ 5V), and DIMM (dimming) must have a low logic level (connect to minus or leave just not involved).
For dimming (dimming), it is necessary to give a high logic level to the ENA contact, and to the DIMM send a PWM signal or an analog signal, taking into account that the dimming connection circuit is inverse (0-on, 5V-off).

    Добрый день. Подскажите, данная плата умеет повышать напряжение на выходе,  относительно напряжения на входе?

      Добрый. Данная плата понижающая. Входное напряжение 10..30 В , выходное около 9 в.
      В LED лампах подсветки для мониторов применяется последовательно-параллельный способ подключения светодиодов. В каждой параллельной ветке по 3 светодиода последовательно.

        Там нет общего минуса между входом и выходом? Кажется, плюс входа и плюс выхода общие.
