describe

MT7932 is a single-stage, high power factor (PF), primary side controlled AC to DC LED driver chip. MT7932 integrates on-chip power factor correction (PFC) function and operates in intermittent conduction mode, achieving high power factor and low harmonic distortion (THD). 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.

MT7932 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.
