Product Description

The MP4034 is an offline regulator that provides accurate constant-current regulation. The LED driver circuit design is simplified by removing the optocoupler and the secondary feedback components. The MP4034 has an integrated 700V MOSFET. Its variable off-time control allows a flyback converter to operate in discontinuous conduction mode (DCM). The MP4034 also features complete protection functions such as VCC under-voltage lockout, over-voltage protection, over-temperature protection, and open-loop protection. The MP4034's variable switching frequency provides natural spectrum shaping to smooth the EMI signature, which can reduce the EMI filter’s size and cost.
