9W DVD power supply using TNY267P
February 4, 2004
13 Conducted EMI
EMI was tested at room temperature, 230 VAC input, during normal operation. Note the
very lower EMI (>12 dB margin), especially with output grounded, in spite of having no
common mode choke, no Y-cap, and no X-cap. The excellent EMI is possible with
TinySwitch-II because of its built-in frequency jitter.
