Hello Team, I need to design 3 drivers types: TYPE I: 1) Input voltage (VAC): 110-240; 2) Power rating (W): 20w; 3) Output current (mA): 320 mA; 4) Output voltage(V): 36-60 Vdc; 5) PFC / iTHD: >90% / <10%; TYPE II: 1) Input voltage (VAC): 110-240; 2) Power rating (W): 50w; 3) Output current (mA): 840 mA; 4) Output voltage(V): 36-60 Vdc; 5) PFC / iTHD: >90% / <10%; Type III: this for outdoor application like Street Light: 1) Power rating (W): 70w; 2) Output current (mA): 1.4 A; 3) Input voltage (VAC): 110-308 4) PFC / iTHD: >90% / <10% Please tell me how I can to start the design, what are your suggestions, Waiting your comments

For the type I and II power supply we can suggest combination PFC + flyback or PFC + quasi resonant flyback controllers. Please refer to our datasheets NCP1927 integrates the primary side control blocks − Power factor correction (PFC) and flyback controllers with sequencing circuitry

or

NCP1937 integrates power factor correction (PFC) and quasi−resonant flyback functionality necessary to implement a compact and highly efficient Switched Mode Power Supply .

For the type III we can suggest the NCL30002 a switch mode power supply controller intended for low to medium power single stage power factor (PF) corrected LED Drivers .
