Key Application Considerations
TinySwitch-II vs. TinySwitch
Table 2 compares the features and performance differences
between the TNY254 device of the TinySwitch-II family with
the TinySwitch-II family of devices. Many of the new features
eliminate the need for or reduce the cost of circuit components.
Other features simplify the design and enhance performance.
Design
Output Power
Table 1 (front page) shows the practical continuous output
power levels that can be obtained under the following
conditions:
TinySwitch-II vs. TinySwitch
1. The minimum DC input voltage is 90 V or higher for
85 VAC input, or 240 V or higher for 230 VAC input or
115 VAC input with a voltage doubler. This corresponds to
a ?lter capacitor of 3 μ F/W for universal input and 1 μ F/W
for 230 VAC or 115 VAC with doubler input.
2. A secondary output of 5 V with a Schottky recti?er diode.
3. Assumed ef?ciency of 77% (TNY267 & TNY268), 75%
(TNY265 & TNY266) and 73% (TNY263 & TNY264).
4. The parts are board mounted with SOURCE pins soldered
to suf?cient area of copper to keep the die temperature at
or below 100 ° C.
In addition to the thermal environment (sealed enclosure,
ventilated, open frame, etc.), the maximum power capability of
TinySwitch-II in a given application depends on transformer
