|
Intelligent Lighting Applications Guide 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 PD78F8024 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 drive 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.
