45 W adapter demo board
Using the new 800 V CoolMOS⢠P7 and ICE2QS03G quasi-resonant PWM controller
Measurements
Figure 23
Low line (100VAC), Full load (45 W) showing normal full load operation of the adapter. This is the
worst case peak current that the primary MOSFET Q1 will encounter during normal operation.
CH1 (Yellow): Q1 VDS
CH2 (Cyan):
Q1 IDS
CH3 (Magenta): Q1 VGS
Figure 24
High line (265 VAC), Full load (45 W) showing normal full load operation of the adapter. This is the
worst case peak drain source voltage that the MOSFET will see under normal operating conditions.
CH1 (Yellow): Q1 VDS
CH2 (Cyan):
Q1 IDS
CH3 (Magenta): Q1 VGS
