MT79332 Overview
MT79332 is a single-stage，primary side control AC-DC LED driver with active power factor correction. MT79332 integrates on-chip PFC circuit operates in critical conduction mode (CRM) to achieve high power factor and reduce the power MOSFET switching loss. With MAXIC Proprietary control technique, precision LED current is achieved without secondary side sense and feedback circuit including opto-coupler.
