内同步整流器CXSU63272超低静态电流低至1uA的高效同步升压变换器输出到输入反向电流保护同步MOSFET提供了最高的效率

CXSU63272是一款超低静态电流低至1uA的高效同步升压变换器。它能够从低电压源（即0.4A，5V输出）输出至少2W的功率。它还具有一个真正的关闭功能，在关闭和输出短路条件下断开输入和输出。这消除了外部MOSFET及其控制电路的需要，以断开输入与输出，并提供强大的输出过载保护。

       CXSU63272 is a high efficiency synchronous step-up converter with ultra- low quiescent current down to 1uA. It is capable of delivering at least 2W of power from a low voltage source, i.e. 0.4A at 5V output. It also features a true-shutofffunction that disconnects the input from output, during shutdown and output short-circuit conditions. This eliminates the need for an external MOSFET and its control circuitry to disconnect the input from output and provides robust output overload protection. A switching frequency of 1.4MHz minimizes solution footprint by allowing the use of tiny and low profile inductors and ceramic capacitors. An intemal synchronous MOSFET provides highest efficiency and with a current mode control that is internally compensated, external parts count is reduced to minimal. With the ultra-low IQ feature, CXSU63272 is ideal for solution that requires low standby power and compact board size such as loT applications.  CXSU63272 is housed in a SOT23-6 and DFN2x2-6 package
