Description
The CoolSET
®
F3 ELJ version is the enhanced LJ version
for system noise. It retains all the features of LJ series
such as BiCMOS technologies, active burst mode,
frequency jitter, propagation delay compensation, built-in
soft start, auto-restart protection for over load and open
loop, latch off protection for over voltage, over
temperature and short winding, external latch off enable,
built-in and extendable blanking time for short period of
over power, etc. It is target for low power SMPS
application such as Off-Line Battery Adapters, DVD player
and recorder, set-top box, auxiliary power supply, etc. The
ELJ version has implemented some noise resist
techniques to the IC such that it is more robust to the
system noise which is generated during system ESD test,
lightning surge test, transient test, etc.
