七,功能概述Xvt嘉泰姆

SYNCHRONOUS RECTIFIERXvt嘉泰姆
The device integrates an N-channel and a P-channel MOSFET transistor to realize aXvt嘉泰姆
synchronous rectifier. Because the commonly used discrete Schottky rectifier is replaced withXvt嘉泰姆
a low RDS(ON) PMOS switch, the power conversion efficiency reaches 96%. To avoidXvt嘉泰姆
ground shift due to the high currents in the NMOS switch, two separate ground pins are used.Xvt嘉泰姆
The reference for all control functions is the GND pin. The source of the NMOS switch isXvt嘉泰姆
connected to PGND. Both grounds must be connected on the PCB at only one point close toXvt嘉泰姆
the GND pin. A special circuit is applied to disconnect the load from the input duringXvt嘉泰姆
shutdown of the converter. In conventional synchronous rectifier circuits, the backgate diodeXvt嘉泰姆
of the high-side PMOS is forward biased in shutdown and allows current flowing from theXvt嘉泰姆
battery to the output. This device however uses a special circuit which takes the cathode ofXvt嘉泰姆
the backgate diode of the high-side PMOS and disconnects it from the source when theXvt嘉泰姆
regulator is not enabled (EN = low).Xvt嘉泰姆
The benefit of this feature for the system design engineer is that the battery is not depletedXvt嘉泰姆
during shutdown of the converter. No additional components have to be added to the designXvt嘉泰姆
to make sure that the battery is disconnected from the output of the converter.Xvt嘉泰姆
