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 18W. The combination of optimized reasonable circuit design and bipolar facture technology with high performance and price ratio economizes the whole cost ultimately.
Pinout
Characteristics
1. Set-in high-voltage power switch tube of 700V and few peripheral components
2. With the modulation of lock pulse width, the testing is according to the pulse limit current.
3. With the function of output frequency reduction, the non-output power consumption can be less than 0.3W.
4. Inner-built ramp and anti-feedback compensation function
5. The independent upper-limit current testing controller deals with over-current and over-load of the controller real-timely.
