PS6203
PWM Controller of High-performance Current Mode
Product Specification
GENERAL DESCRIPTION
PWM controller of high-performance current mode is
specially designed for AC/DC transformer with high
performance and price ratio, which supplies continuous
output power of 12W within the range of wide-voltage
between 85V and 265V, the output power of peak value
can be up to 15W. The combination of optimized
reasonable circuit design and bipolar facture technology
with high performance and price ratio economizes the
whole cost ultimately. The power controller can be applied
to the typical fly-back circuit topology so as to form a
simple AC/DC transformer. When the output power is
lower, IC will reduce the working frequency automatically,
therefore, the standby power consumption becomes
extremely low. When the power tube is closed, the interior
circuit will bias it reversely, utilize the characteristic of high
pressure resistance CB of bipolar
transistor directly, and
improve its pressure resistance capacity to the high
voltage of 800V, which ensures the security of the power
tube.
.
Meanwhile, the perfect function of overload and
saturation prevention is provided inside of IC, which can
keep away some abnormal status, such as overload,
saturation of transformer, and output short circuit, so as to
improve the reliability of the power supply. The current
limit and clock frequency can be set up by exterior
components.
