Two input power curves giving the typical input power versus ambient temperature are showed below;
Vin=85Vac~265Vac (Figure 31) and Vin=230Vac+/-15% (Figure 32). The curves are derived based on a typical
discontinuous mode flyback model which considers either 50% maximum duty ratio or 100V maximum secondary
to primary reflected voltage (higher priority). The calculation is based on no copper area as heatsink for the device.
The input power already includes the power loss at input common mode choke, bridge rectifier and the
CoolMOS.The device saturation current (I
To estimate the output power of the device, it is simply multiplying the input power at a particular operating ambient
temperature with the estimated efficiency for the application. For example, a wide range input voltage (Figure 31),
operating temperature is 50°C, estimated efficiency is 85%, then the estimated output power is 42W (49W * 85%).
