Design Idea DI-39 TOPSwitch-GX 13 W, Universal Input DVD Supply with 70 mW No-load

Design Highlights

• High efficiency multi-ouptut flyback (77 minimum)

• Topology scalable to higher powers

• Excellent cross-regulation

• Excellent input no-load consumption <70 mW input

• 132 kHz switching frequency allows smaller transformer

• Frequency jitter eliminates common-mode EMI choke

• >10 dB margin against CISPR22-B conducted EMI with artificial hand grounding
