Description

The EDC-LL324 is a smart LED driver IC capable of driving up to four LED strings in either buck or boost configuration. It combines four independent 64-MHz current-controlling state machines, an AVR® compatible micro controller, and four gate driver pairs for external low-RDS(on) P/N-channel MOSFETs supporting LED currents up to 5A.

Features

• 4 independent N-channel / 4 independent P-channel MOSFET drivers
