LED lighting designers and engineers are constantly looking for ways to reduce the cost and the size of the power management solution for multi-LED applications. NEC Electronics' solution is a 4-channel constant-current driver with an embedded 8-bit flash microcontroller integrated into a single package to maximize savings of both cost and space.

The µPD78F8024 microcontroller has a wide input voltage range from 9 to 38V and supports both buck and boost topologies to drive up to 40 high-power LEDs at currents reaching over 1.5A. Each constant-current driver implements an individual hardware hysteretic regulator controller with switching frequency up to 1 MHz, while the flash microcontroller can control each channel through PWM signals to enable dimming, flashing, and strobing sequences.

The Applilet EZ code generator is a free, user-friendly development tool that generates software automatically to control the four channels of the µPD78F8024 microcontroller.

The CA78K0 includes the PM+ project manager and a compiler and assembler.

WriteEZ3 is a programming GUI for the EV-K0-HCD evaluation kit.

A parameter file is required to program the device.

The IECUBE is a full-function emulator used to efficiently debug both hardware and software. This high-performance emulator includes the NEC Electronics debugger and a simple flash programmer. It's compact and lightweight enough to fit in your hand, and is a cost-effective solution. Furthermore, an incorporated self-testing tool allows for easy maintenance.
