Abstract
The member for a synchronous rectifier bridge () typically includes at least first and second connection terminals (B+, P), at least one field-effect transistor () having source and drain electrodes () respectively connected to the first and second terminals (B+, P), and at least one comparator for comparing at least a first voltage source having a predetermined reference voltage and at least a first voltage difference between the voltages applied to the first and second terminals (B+, P) and having an output connected to a gate electrode () of the transistor (). The member () further includes at least one load pump () providing, from the applied voltages, at least one supply voltage (VH, VL), of an amplifier from said applied voltages.
