MT7933 Datasheet (Maxic Technology)

MT7933, AC-DC LED Driver

MT7933 is a single-stage，primary side control AC-DC LED driver with active power factor correction.

MT7933 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, prec
