Once the V CC capacitor is charged to the start-up voltage V CC-start (11V), the IC starts driving the MOSFET. Both internal current sources are switc

Operation The supply can run in three different modes depending on the output power: • Quasi-Resonant mode (QR) The QR mode, described above, is used

Safe-Restart Mode This mode is introduced to prevent the components from being destroyed during eventual system fault conditions. It is also used for

In the active period the energy is transferred to the secondary and stored in the buffer capacitor C STAB in front of the linear stabilizer (see Figur

For a more detailed description of one burst cycle, three time intervals are defined: • t1: Discharge of V CC when gate drive is active During the fi

Protection Events The SMPS IC 7520 has the following protection features: Demagnetization sense This feature guarantees discontinuous conduction mode

Over Voltage Protection The Over Voltage Protection ensures that the output voltage will remain below an adjustable level. This works by sensing the a
