MT7933 driver equivalent, ac-dc led driver.
* Single-stage Active PFC for high power factor and low THD
* Primary side control eliminates opto-coupler
* High precision LED current (+/-3%)
* Critical.
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 lo.
