SANKEN ELECTRIC : News Release
October 18, 2002
Sanken introduces "STR-W 6800
Series ICs" for Quasi-Resonant
Switch Mode Power Supply that
enables high efficiency, low noise
and drastic save of power
consumption at the time of stand-by.
Sanken Electronic Co., Ltd. has developed
"STR-W 6800 Series ICs" for Quasi-
Resonant SMPS with high efficiency and
low noise that consume only one-tenth of
the electric power compared with that of
our conventional devices. Shipments of the
new series will begin from October 25,
2002. Initially Sanken is planning to begin
monthly volume production of 100,000 per
month. The monthly sales volume will be
increased to 500,000 by the end of 2002.
The sample price is three hundred (300)
yen per piece.
Recently there has been a strong demand for save of power
consumption for TVs, VTRs and other electric appliances. Especially in
the case of remote controlled home electric appliances, the annual
stand-by power consumption to electricity all told is quite high
although the absolute consumption itself is small. That is why
demand for reduction of stand-by power consumption is strong these
days.
Quasi-Resonant SMPS with low noise, is widely used as the video
signals of AV equipments such as TV, VTR are fragile to noise.
However, the conventional Quasi-Resonant SMPS has a drawback; its
efficiency tends to be degraded by the high operating frequency at
