DER-7
9.2 Cross Regulation
Minimum and maximum output voltages were recorded, while cycling the unit on/off,
start/stop, pause/run, chapter jump, and fast forward. The tests were done at room
temperature, 115 VAC input. Note the tight regulation of the PI 3.3V output in spite of the
low-cost, simple zener regulation. This is possible with TinySwitch-II because of its
unique feedback scheme.
10 Thermal Performance
Temperature of TOP267 during normal operation, case of DVD player closed.
Temperature rise is less than 30
11 Minimum Operating Voltage and peak power margin
The unit is capable of starting and running as low as 68 VAC. This indicates plenty of
margin for the DVD player’s peak power requirements, as flyback power supplies deliver
less maximum power when the AC input voltage is low.
