ZLED7330KIT-D1

The ZLED7330KIT-D1 is a demo kit for ZLED7330 high current 40V LED driver with switch dimming. The ZLED7330 is designed for applications requiring high brightness and high current. It can efficiently drive a single LED or multiple series connected LEDs from a voltage input higher than the LED forward voltage. The ZLED7330 provides a switch dimming function. It detects external switch action to adjust output current, allowing dimming functionality to be achieved without changing the original lighting system circuitry. The switch dimming is implemented in either two level mode or three level mode. The output current of every level and the total number of levels are customer selected by setting the corresponding input conditions of DIM1 and DIM2 pin. The ZLED7330 can also minimize bill of material costs because very few external components are required for most applications. Only a resistor, a diode, an inductor and three capacitors are needed for a typical basic application.
