Revision History: 2004-06-11 DatasheetPrevious Version:
CoolSET™-F2
Product HighlightsBest in class in DIP8, DIP7, TO220 and DSO16/12
packagesNo heat-sink required for DIP8, DIP7 and DSO16/12Increased creepage distance for TO220, DIP7 and
DSO16/12Isolated drain for TO220 packagesLowest standby power dissipationEnhanced protection functions with
Auto Restart Mode
DescriptionThe second generation CoolSET™-F2 provides several
special enhancements to satisfy the needs for low power
standby and protection features. In standby mode
frequency reduction is used to lower the power
consumption and support a stable output voltage in this
mode. The frequency reduction is limited to 20kHz/21.5
kHz to avoid audible noise. In case of failure modes like
open loop, overvoltage or overload due to short circuit the
device switches in Auto Restart Mode which is controlled by
the internal protection unit. By means of the internal precise
peak current limitation, the dimension of the transformer
and the secondary diode can be sized lower which leads to
more cost effective for the overall system.
