SDC605 PWM controller

2.         A variety of environmental protection, energy saving internal power supply of small appliances (such as the induction cooker, microwave ovens, etc)

1.         Adaptor (for example, travel charger, out power station)

Offline AC/DC flyback converter for

13.     Continuous wide-voltage output power reaches 12W, and the output power of peak value arrives at 18W.

12.     VCC over-voltage automatic limit

11.     Low startup and operating current

10.     Few peripheral components

9.         Startup is accomplished with the magnification function of the switch power tube, and the power consumption of startup resistance is reduced more than10 times.

8.         Set-in heat protection circuit

7.         Set-in current limit resistance with temperature compensation, which makes the current limit precise

6.         The period emission pole is turned off and it outputs by deflected voltage, and the pressure resistance of the power tube is improved.

5.         The independent upper-limit current testing controller deals with over-current and over-load of the controller real-timely.

4.         Inner-built ramp and anti-feedback compensation function.

3.         With the function of output frequency reduction, the non-output power consumption can be less than 0.25W.

2.         With the modulation of lock pulse width, the testing is according to the pulse limit current.

1.         Set-in high-voltage power switch tube of 700V and few peripheral components.

Now the standard encapsulation and the environmental protection leadless encapsulation that meets European standard of  DIP8 are supplied.

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 5W within the range of wide-voltage between 85V and 265V.
