一,产品概述(General Description)         UP2嘉泰姆
   CXSU63039 is a high efficiency synchronous boost regulator that convertsUP2嘉泰姆

down to 2.5V input and up to 5.5V output voltage. It adopts NMOS for theUP2嘉泰姆

main switch and PMOS for the synchronous switch. It can disconnect the UP2嘉泰姆

output from input during the shutdown mode..UP2嘉泰姆

  It integrates 5A power MOSFET and can output 5V 2.5A with Li-Battery input.UP2嘉泰姆

七,功能概述UP2嘉泰姆

SYNCHRONOUS RECTIFIERUP2嘉泰姆
The device integrates an N-channel and a P-channel MOSFET transistor to realize aUP2嘉泰姆
synchronous rectifier. Because the commonly used discrete Schottky rectifier is replaced withUP2嘉泰姆
a low RDS(ON) PMOS switch, the power conversion efficiency reaches 96%. To avoidUP2嘉泰姆
ground shift due to the high currents in the NMOS switch, two separate ground pins are used.UP2嘉泰姆
The reference for all control functions is the GND pin. The source of the NMOS switch isUP2嘉泰姆
connected to PGND. Both grounds must be connected on the PCB at only one point close toUP2嘉泰姆
the GND pin. A special circuit is applied to disconnect the load from the input duringUP2嘉泰姆
shutdown of the converter. In conventional synchronous rectifier circuits, the backgate diodeUP2嘉泰姆
of the high-side PMOS is forward biased in shutdown and allows current flowing from theUP2嘉泰姆
battery to the output. This device however uses a special circuit which takes the cathode ofUP2嘉泰姆
the backgate diode of the high-side PMOS and disconnects it from the source when theUP2嘉泰姆
regulator is not enabled (EN = low).UP2嘉泰姆
The benefit of this feature for the system design engineer is that the battery is not depletedUP2嘉泰姆
during shutdown of the converter. No additional components have to be added to the designUP2嘉泰姆
to make sure that the battery is disconnected from the output of the converter.UP2嘉泰姆
