CRE6203

CRE6203 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. . FEATURES  Set-in high-voltage power switch tube of 800V and few peripheral components. according to the pulse limit current. . .  With the modulation of lock pulse width, the testing is  With the function of output frequency reduction, the nonoutput power consumption can be less than 0.3W.  Inner-built ramp and anti-feedback compensation function. .  The independent upper-limit current testing c...
