INTEGRATED FET AND DRIVER

摘要

The invention relates to a low side component and a synchronous dc voltage converter circuit. A sync FET (8) is controlled by a driver (32) powered between high and low voltage power connections (134, 138). A timing circuit (150) controls the driver circuit in accordance with a signal on a control input. The driver circuit (32) is isolated from the timing circuit (150), for example by a level shift circuit (136) and the low voltage power connection (138) of the driver circuit is directly connected to the source (108) of the sync FET (8). This may reduce transient voltage effects.
