The next converter stroke is started only after demagnetization of the transformer current zero current switchingwhile the drain voltage has reached the lowest tes1507p to prevent switching losses green function.
V CC start level. Typically, 3 Watts can be achieved for a. V CC management pin 1.
The IC will activate the power. Typically, 3 Watts can be achieved for a 75 W converter with an output power of mW. Demagnetization management pin 4. Once the drain voltage exceeds tex1507p M-level mains-dependent operation-enabling levelthe start-up current source will continue charging capacitor C VCC switch S1 will be openedsee Fig.

The moment the voltage on pin V CC drops below the. The primary resonant circuit of primary inductance and drain capacitor ensures this quasi-resonant operation.
Supply capacitor C VCC is charged. To prevent very high frequency operation at lower loads.
Start-up current source pin 8. The TEA is the controller of a compact flyback.
To prevent very high frequency operation at lower loads, the quasi-resonant operation changes smoothly in fixed frequency PWM control. The TEA operates in multi modes.
The IC supply is taken over by the auxiliary winding as soon as the tda1507p voltage reaches its intended level and the IC supply from the mains voltage is subsequently stopped for high efficiency operation green function.
At very low power standby levels, the frequency is. Start-up, mains enabling operation level and undervoltage lock out see Figs. At very low power standby levels, the frequency is controlled down, via the VCO, to a minimum frequency of about 6 kHz. The next converter stroke is started only after. Initially, the IC is self supplying from the rectified tea15507p.
An auxiliary winding of the transformer provides demagnetization tex1507p and powers the IC after start-up. Supply capacitor C VCC is charged by the internal start-up current source to a level of about 4 V or higher, depending on the drain voltage. Duty cycle control pin 3.
Supply management All internal reference voltages are derived from a temperature compensated, on-chip band gap circuit. Inhibiting the auxiliary supply by external means causes the converter to operate in a stable, well-defined burst mode. The IC supply is taken over by the auxiliary. All internal reference voltages are derived from a.
File under Integrated Circuits, IC Start-up, mains enabling operation level and. Inhibiting the auxiliary supply by external means causes.
The design can be optimized in such a way that zero voltage switching can be reached over almost the universal mains range.
