DLD101 Typical Application Circuit VCC Supply The DLD101 has been designed primarily for solid state lighting applications, to be used as a current sink circuit solution for LEDs. It features a N-channel MOSFET capable of 1A drive current and a prebiased NPN transistor (which allows direct connection to the base, or via a series base resistor). LED String 4 3 1 2 G Figure 12 shows a typical application circuit diagram for driving an LED or string of LEDs.
