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.

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 fi lter capacitor of 3 μF/W for universal input and 1 μF/W
for 230 VAC or 115 VAC with doubler input.
2.
A secondary output of 5 V with a Schottky rectifi er diode.
3.
Assumed effi ciency of 77% (TNY267 & TNY268), 75%
(TNY265 & TNY266) and 73% (TNY263 & TNY264).
4.
The parts are board mounted with SOURCE pins soldered
to suffi 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

Advantages
Smaller transformer for low cost
Ease of design
Manufacturability
Optimum design for lower cost
Lower EMI minimizing fi lter
component costs
Practically eliminates audible noise with ordinary dip
varnished transformer – no special
construction or gluing required
Prevents power on/off glitches
Increases power capability and
simplifi es design for high volume
manufacturing
Limits output short-circuit current to less than full
load current
No output diode size penalty
Protects load in open loop fault conditions
No additional components required
Allows TinySwitch-II to be powered from a low
voltage bias winding to improve effi ciency and to
reduce on-chip power dissipation
Greater immunity to arcing as a result of dust,
debris or other contaminants build-up
