Said to be the world’s first intelligent constant high-current driver (HCD) with a microcontroller (MCU), the HCD/LED MCU was codeveloped with NEC Electronics America and can be used in lighting applications that employ multiple LEDs or industrial control applications such as stepping motors, solenoid drives, and switch-mode power supplies. The new device combines an NEC Electronics 8-bit All Flash microcontroller with a four-channel HCD that helps reduce device size and system costs. The product’s high level of integration reduces the number of external components and opens up board space for other components. In addition to supporting a wide input voltage range from 9 to 38 V, the flexible four-channel architecture also enables designs using both buck and boost regulator topologies. The µPD78F8024 HCD/LED MCU is available in a 64-pin LQFP. Future Lighting Solutions, www.futurelightingsolutions.com/NEC
