一.产品概述
JTMB8896 is a high-performance current mode PWM control IC designed for AC/DC convertor,
which built-in high-voltage power switch tube and supplies continuous output power of 10W within
the range of wide-voltage between 85V and 300V, the output power of peak value can be up
to 12W.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 flyback circuit topology so as to form a simple AC/DC transformer. IC
circuit can use the power switch tube itself within a larger version of startup, greatly reduces the
power loss of starting resistance .IC built-in PFM function that when the output power increases
then the working frequency increases, thus reducing switching loss and achieving high
efficiency when the power output decreases. The PFM function combination of patent drive circuit
that can easily meet "of energy Star 2.0" strict requirements. When VCC reaches 12V, the chip
internal over voltage protection activates and limits the output voltage rising. That can prevent
the too high output voltage because the light coupling or the feedback circuit damaged. The
circuit built-in the input voltage compensation function, which realizes the constant output
power limiting in the whole power grid conditions. In the IC internal that provides the overload and
the perfect saturation function. It can real time control van overload, transformer saturation,
output short circuit in abnormal condition, so improving the reliability of power supply. IC has
integrated the internal temperature protection function, when the system is overheating, the
output power will be lower, or shuts down the output. We can provide meeting ROHS and
green environmental protection requirements of DIP-8 standard.
