THX202H

Switching Power Controller IC

 

Characteristics 

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

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

current. 

 With the function of output frequency reduction, the non-output power consumption can 

be less than 25W. 

 Inner-built ramp and anti-feedback compensation function 

 The independent upper-limit current testing controller deals with over-current and 

over-load of the controller real-timely. 

 The period emission pole is turned off and it outputs by deflected voltage, and the 

pressure resistance of the power tube is improved. 

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

limit precise 

 Set-in heat protection circuit 

 Startup is accomplished with the magnification function of the switch power tube, and 

the power consumption of startup resistance is reduced more than10 times. 

 Few peripheral components 

 Low startup and operating current 

 VCC over-voltage automatic limit 

 Wide-voltage output power reaches 5W, and the narrow-voltage output power reaches 

8W. 

 

Applied Field 

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

 As internal power source of environmental-protection and energy-saving type of 

household appliances (such as electromagnetic oven and microwave oven)
