z Set-in high-voltage power switch tube of 700V and few peripheral components z With the modulation of lock pulse width, the testing is according to the pulse limit current. z With the function of output frequency reduction, the non-output power consumption can be less than 0.3W. z Inner-built ramp and anti-feedback compensation function z The independent upper-limit current testing controller deals with over-current and over-load of the controller real-timely. z The period emission pole is turned off and it outputs by deflected voltage, and the pressure resistance of the power tube is improved. z Set-in current limit resistance with temperature compensation, which makes the current limit precise z Set-in heat protection circuit z Startup is accomplished with the magnification function of the switch power tube, and the power consumption of startup resistance is reduced more than10 times. z Few peripheral components z Low startup and operating current z VCC over-voltage automatic limit z Continuous wide-voltage output power reaches 12W, and the output power of peak value arrives at 18W. Applied Field z Adaptor (for example, travel charger, out power station) z Open Frame (for example, DVD, DVB)
