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)
