GW6203

Микросхема GW6203

GW6203 - PWM Controller of High-performance Current Mode, DIP-8

 

Описание, параметры, характеристики

• 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 0.3W.
• 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
• Continuous wide-voltage output power reaches 18W, and the output power of peak value arrives at 24W.
• Compatible with THX203/RM6203 

 

Применение

• Adaptor (for example, travel charger, out power station)
• Open Frame (such as electromagnetic oven, microwave oven and etc.)
