... NXP Semiconductors components R Furthermore, a primary stroke is started only in a valley of the secondary ringing. This valley switching principle minimizes capacitive switch-on losses. 8.1 Start-up and Underoltage lockout Initially, the IC is self supplying from the rectified mains voltage. The IC starts switching as soon as the voltage on pin V the auxiliary winding of the transformer as soon as V from the line is stopped for high efficiency operation ...

... NXP Semiconductors As soon as the oscillator voltage is high again and the secondary stroke has ended, the circuit waits for a low drain voltage before starting a new primary stroke. Figure 4 secondary stroke and the RC voltage. The primary stroke starts some time before the actual valley at low ringing frequencies, and some time after the actual valley at high ringing frequencies ...

... NXP Semiconductors 8.10 OverVoltage Protection (OVP) Overvoltage protection can be achieved in the application by pulling pin REG above its normal operation level. The current primary stroke is terminated immediately, and no new primary stroke is started until the voltage on pin REG drops to its normal operation level. ...
