Two input power curves gives typical input power versus ambient temperature are showed below;
Vin=85~265Vac(Figure
discontinuous mode flyback model which considers 150V maximum secondary to primary reflected voltage. The
calculation is based on 232mm
power loss at input comman mode choke and bridge rectifier and the CoolMOS
current(I
To estimate the out power of the device, it is simply multiplying the input power at a particulary ambient
temperature with the estimated efficiency for the application. For example, a wide range input
operating temperature is 50 °C, estimated efficiency is 80%,the output power is 24.8W(31W*0.80)
