describe

MT7936 is a single-stage, high power factor, primary side controlled AC to DC LED driver chip. MT7936 integrates on-chip power factor correction (PFC) function and operates in critical conduction mode, achieving high power factor and reducing power MOS switching losses.

By utilizing the unique control technology of Meixinsheng Technology (patented), LED current can be precisely modulated without the need for optocouplers and secondary sensing devices.

MT7936 simultaneously implements various protection functions, including overcurrent protection (OCP), overvoltage protection (OVP), short circuit protection (SCP), and overheat protection (OTP), to ensure the reliable operation of the system.
