After the leading edge blanking time, the short winding
protection circuit is activated. If the ‘sense’ voltage
exceeds the short winding protection voltage V swp , the
converter will stop switching. Once V CC drops below the
UVLO level, capacitor C VCC will be recharged and the
supply will restart again. This cycle will be repeated until
the short-circuit is removed (safe restart mode).
The short winding protection will also protect in case of a
secondary diode short-circuit.

OverTemperature Protection (OTP)
An accurate temperature protection is provided in the
to the following formula: I DEM ≈ --------------- ≈ --------------------------
Fig.10 OPP correction curve.
OverCurrent Protection (OCP)
The cycle-by-cycle peak drain current limit circuit uses the
external source resistor to measure the current accurately.
This allows optimum size determination of the transformer
core (cost issue). The circuit is activated after the leading
edge blanking time, t leb . The OCP circuit limits the ‘sense’
voltage to an internal level.
OverPower Protection (OPP)
During the primary stroke, the rectified mains input voltage
is measured by sensing the current drawn from pin DEM.
This current is dependent on the mains voltage, according
V aux N × V mains
R DEM R DEM
N aux
where: N = ------------
N p
The current information is used to adjust the peak drain
current, which is measured via pin I sense . The internal
compensation is such that an almost mains independent
maximum output power can be realized.
The OPP curve is given in Fig.10.

circuit. When the junction temperature exceeds the
thermal shutdown temperature, the IC will enter the safe
restart mode.
When the V start level is reached, switching starts again.
This process is repeated as long as the OTP condition
exists.
