Abstract
A synchronous dc—dc converter converts an input dc voltage to an output dc voltage. A control FET (6) and a sync FET (8) are connected in series between input dc voltage terminals (2,4). An alternating control signal input from a control circuit (18) controls the control and sync FETs (6,8) to be switched on alternately. At least one driver (30, 32) is provided to drive the FETs (6,8). In response to a change in the alternating control signal of a predetermined polarity, the driver (32) switches off the sync FET (8), and then the driver (30) waits for the trigger signal before switching on the control FET (6).
