Document Type and Number:
Japanese Patent JP4247640
Kind Code:
B2
Abstract:
The present invention discloses a power supply circuit initiating an oscillation on a primary side of the power supply circuit upon receipt of a startup signal, comprising: a detecting module receiving an output voltage from the power supply circuit for detecting whether the output voltage is below a predetermined voltage; a power supply switching module turning OFF a main power supply of the power supply circuit when the detecting module determines the output voltage to be below the predetermined voltage; and a detection invalidating module invalidating the detecting of the detecting module from the receipt of the predetermined startup signal to the output voltage becomes above or equal the predetermined voltage.
