THX203H THX203 DIP-8 Switching Power Controller IC AY66

Description:

* 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 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)
