... NXP Semiconductors 8. Functional description The SSL152x family 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 opto coupler feedback ...

... NXP Semiconductors 8.4 Valley switching A new cycle is started when the primary switch is switched on (see certain time (determined by the oscillator voltage RC and the internal regulation level), the switch is turned off and the secondary stroke starts. The internal regulation level is determined by the voltage on pin REG. ...

... NXP Semiconductors Figure 5 the output voltage V the factor N (determined by the turns ratio of the transformer). system switches exactly at 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 8.9 OverTemperature Protection (OTP) 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. ...
