45 W adapter demo board
Using the new 800 V CoolMOS™ P7 and ICE2QS03G quasi-resonant PWM controller
800 V CoolMOS™ P7 overview
Q1
Figure 8
45 W adapter bottom using DPAK at 45 W load and 120 VAC. Q1 shown above in the black box is the
flyback converter primary MOSFET. Note the MOSFET Q1 is receiving some heating from the
surrounding components which contributes to the higher DPAK temperature.

Figure 9 45 W adapter top using FullPAK at 45 W load and 120 VAC. Q1 shown above in the black box is the
flyback converter primary MOSFET.
Q1
Figure 10 45 W adapter bottom using FullPAK at 45 W load and 100 VAC. The DPAK footprint is shown and the
local PCB temperature rise can be seen which further increases the DPAK temperature.
