一,产品概述(General Description)      mk8嘉泰姆
mk8嘉泰姆
       CXSU6337  CXSU6337C series are CMOS-based PFM step-up DC-DC Converter. The converter can mk8嘉泰姆

start up by supply voltage as low as 0.8V, and capable of delivering maximummk8嘉泰姆

 200mA output current at 3.3V output with 1.8V input Voltage. Quiescent mk8嘉泰姆

current drawn from power source is as low as 5.5uA. All of these features make mk8嘉泰姆

CXSU6337 series be suitable for the portable devices, which are supplied by amk8嘉泰姆

 single battery to four-cell batteries.To reduce the noise caused by the switch mk8嘉泰姆

regulator, CXSU6337 is well considerate in circuit design and manufacture,mk8嘉泰姆

so that the interferer toother circuits by the device is reduced greatly.mk8嘉泰姆

       CXSU6337 integrates stable reference circuits and trimming technology, so itmk8嘉泰姆

can afford high precision and low temperature-drift coefficient of the output voltage.mk8嘉泰姆

  CXSU6337 is available in SOT-89-3, SOT-23-3, SOT-23-5 and TO-92 packages, mk8嘉泰姆

which is PB free. And in 5-pin packages, such as SOT-23-5, the device can be mk8嘉泰姆

switch on or off easily by CE pin, to minimize the standby supply current.mk8嘉泰姆
