Document Type and Number:
Japanese Patent JP2003526307
Kind Code:
A
Abstract:
The present invention provides a method for preventing a fault condition in a DC-DC converter (10, 20, 50) having a first secondary winding (Ns1) coupled to a first synchronous rectifier (SQ1) and a second secondary winding (Ns2) coupled to a second synchronous rectifier (SQ2). The first synchronous rectifier (SQ1) is turned on based on a voltage across the first secondary winding (Ns1) and is turned off based on a first driver signal. The second synchronous rectifier (SQ2) is turned on based on a voltage across the second secondary winding (Ns2) and is turned off based on a second driver signal. The present invention also provides a DC-DC converter (10, 20, 50) wherein a first control circuit is coupled to and controls the first synchronous rectifier (SQ1) pursuant to the method described above, and a second control circuit is coupled to and controls the second synchronous rectifier (SQ2) pursuant to the method described above.
