GW6203
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 18W within the range of wide-voltage between 85V and 265V, the output power of peak value can be up to 24W. The bination 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 bees 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 700V, which ensures the security of the power...
