ABSTRACT:
An external driving circuit (21) for a bridge type synchronous rectifier circuit (20) having a first and second first synchronous rectifier (Q3,Q4), a primary driving circuit (14), and a pair of totem pole drivers (16,18). The timing signal for the first and second synchronous rectifiers (Q3,Q4) is derived from the external driving circuit (21). The external driving circuit (21) includes a first and second switch drivers (22,24). The external driving circuit (21) is interfaced with the synchronous rectifier circuit (20) by connecting first and second switch drivers (22,24) to the totem pole drivers (16,18). The first and second switch drivers (22,24) provides storage for circuit current which is fully discharged at the appropriate time to facilitate turning on and off the synchronous rectifiers (Q3,Q4).
