About This Product

■Summary

The MP4034 is an offline regulator that provides precise constant current regulation. LED driver circuit design is simplified by eliminating optocouplers and secondary feedback components. MP4034 has a built-in 700V MOSFET. Variable off-time control allows the flyback converter to operate in discontinuous conduction mode (DCM). MP4034 also has rich protection features such as VCC undervoltage lockout, overvoltage protection, overtemperature protection, and open loop protection. The MP4034's variable switching frequency provides natural spectral shaping to smooth EMI characteristics, reducing EMI filter size and cost.

■Features and benefits

・Primary side control without optocoupler or secondary feedback circuit ・Accurate constant current adjustment 700V MOSFET integration with minimal external components ・Variable off-time and peak current control ・550μA high voltage current source ・Output power up to 7W ・Overvoltage protection ・Overheat protection ・Open loop protection ・Natural frequency dithering to improve EMI characteristics ・Low cost and simple external circuit ・SOIC8-7A package

■Available product numbers

・MP4034GS-P MP4034GS-Z ・Part numbers ending in P and Z are the same part. P and Z indicate reel size only
