we will build a new switching power supply, input:90-240VAC; output:48V/10A; PFC>0.95, efficiency>90%. environment temperature: -40C---70C.
Just now, I choose NCP1654+NCP1397. for PFC and LLC control.
and I also want to know if there is another solution for costing and temperature.
An option that you can consider are: for PFC part NCP1653 (Fixed Switching Frequency: 67 kHz = NCP1653A, Fixed Switching Frequency: 100 kHz = NCP1653) and the NCP1398 high performance controller for half bridge LLC resonant converters.
