A controller for a switched mode power supply

A controller (210) for a switched mode power supply (100), the switched mode power supply (100) comprising one or more windings (104, 106, 108). The controller (210) comprising a fixed speed timer (236); a threshold setter configured to a set a threshold for the timer (236) in accordance with a peak...

Beschreibung
Zusammenfassung:	A controller (210) for a switched mode power supply (100), the switched mode power supply (100) comprising one or more windings (104, 106, 108). The controller (210) comprising a fixed speed timer (236); a threshold setter configured to a set a threshold for the timer (236) in accordance with a peak value of a current (304) through one of the one or more windings (106); a secondary stroke detector (252) configured to start the fixed speed timer (236) upon detection of the start of a secondary stroke of the switched mode power supply; a sampler (232, 234) configured to sample a voltage across one of the one or more windings (108) when a count of the fixed speed timer (236) reaches the threshold.
