... NXP Semiconductors 7.2 Pin description Table 3. Symbol V CC GND RC REG AUX SOURCE n.c. DRAIN 8. Functional description The SSL1523A is the heart of a compact flyback converter, with the IC placed at the primary side. The auxiliary winding of the transformer can be used for indirect feedback to control the isolated output. This additional winding also powers the IC. A more accurate control of the output voltage and/or current can be implemented with an additional secondary sensing circuit and optocoupler feedback ...

... NXP Semiconductors at low duty factors is easily realized. For high efficiency, the frequency is reduced as soon as the duty factor drops below its low power threshold. This is accomplished by increasing the oscillator charge time. To ensure that the capacitor can be charged within the charge time, the value of the oscillator capacitor should be limited to approximately 1 nF ...

... NXP Semiconductors Fig 3. Figure 4 the output voltage V the factor N (determined by the turns ratio of the transformer). system switches at the minimum drain voltage for ringing frequencies of 480 kHz, thus reducing the switch-on losses to a minimum. At 200 kHz, the next primary stroke is started at 33 ° before the valley. The switch-on losses are still reduced significantly. ...

... NXP Semiconductors 8.5 Demagnetization 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 the first t suppression may be necessary in applications where the transformer has a large leakage inductance and at low output voltages. ...
