The system operates in discontinuous conduction mode all the time. As long as the
secondary stroke has not ended, the oscillator will not start a new primary stroke. During

be necessary in applications where the transformer has a large leakage inductance and at
low output voltages.
The minimum duty factor of the switched mode power supply is 0 %. The maximum duty
factor is set to 75 % (typical value at 100 kHz oscillation frequency).
The cycle-by-cycle peak drain current limit circuit uses the external source resistor R
measure the current. The circuit is activated after the leading edge blanking time t
protection circuit limits the source voltage to V
current.
The short-circuit winding protection circuit is also activated after the leading edge blanking
time. If the source voltage exceeds the short-circuit winding protection voltage V
stops switching. Only a power-on reset will restart normal operation. The short-circuit
winding protection also protects in case of a secondary diode short circuit.
An accurate temperature protection is provided in the device. When the junction
temperature exceeds the thermal shutdown temperature, the IC stops switching. During
thermal protection, the IC current is lowered to the start-up current. The IC continues
normal operation as soon as the overtemperature situation has disappeared.
