HCD+MCU Reduces Board Space In LED Lighting Apps May 15, 2008
Partnering with Future Lighting Solutions, the company unveils what it is calling the market’s first intelligent constant high-current driver (HCD) with microcontroller (MCU). The HCD/LED MCU targets lighting applications that employ multiple LEDs, as well as stepping motors, solenoid drives, and switchmode power supplies. To reduce the number of external components and system costs, the µPD78F8024 combines an eight-bit All Flash MCU with a four-channel HCD. In addition to supporting an input-voltage range from 9V to 38V, the four-channel architecture also enables designs using both buck and boost regulator topologies. Available in a 64-pin LQFP, samples of the µPD78F8024 are available now starting at $3.50 each/1,000. NEC ELECTRONICS AMERICA INC., Santa Clara, CA. (800) 366-9782.
