Two input power curves gives typical input power versus ambient temperature are showed below;
Vin=85~265Vac(Figure
flyback model which considers 115V maximum secondary to primary reflected voltage(high priority). The calculation is
based on no copper area as heatsink for the device. The input power already includes power loss at input comman mode choke
and bridge rectifier and the CoolMOS
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
°C, estimated efficiency is 85%,the output power is 14.45W(17W*0.85).
