Abstract (en)
[origin: WO2006021726A2] The invention concerns a circuit (30) for detecting an overload in a load supplied by a switched-mode power supply, comprising: a first comparator (25) of a first voltage based on the supply voltage of the load relative to a first threshold (V<SB>FB</SB>), supplying a regulating signal (CT) to a pulse generator (6) controlling the switched-mode power supply; a second comparator (31) of a second voltage relative to a second threshold (V<SB>OLV</SB>), supplying a signal (OVL) indicating the presence of an overload; and means (C33, 34, 35, M35) for automatically controlling said second voltage by a third threshold (V<SB>INI</SB>) lower than the second and higher than the first, and for deactivating the second comparator as long as said automatic control is maintained.
