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.

Output Power
Table 1 (front page) shows the practical continuous output
power levels that can be obtained under the following
conditions:
Table 2.
Comparison Between TinySwitch and TinySwitch-II.
*Not available.
** See typical performance curves.
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
μF/W for universal input and 1 μF/W
for 230 VAC or 115 VAC with doubler input.
A secondary output of 5 V with a Schottky rectier diode.
Assumed efciency of 77% (TNY267 & TNY268), 75%
(TNY265 & TNY266) and 73% (TNY263 & TNY264).
The parts are board mounted with SOURCE pins soldered
to sufcient 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
