Abstract
A DC-DC converter () includes a switching transistor (M) connecting an input power terminal (VIN) to an inductor () that is also connected to an output power terminal (VOUT), a synchronous rectification transistor (M) connected to a junction node () between the inductor () and the switching transistor (M), and a synchronous rectifier control circuit () with an integration capacitor () having a voltage that is charged and discharged by first and second current sources () to track the charging and discharging of the inductor current, thereby generating a synchronous rectifier control signal (SR) that is applied to the synchronous rectification transistor to discharge the inductor current to zero.
