一,产品概述(General Description)      rK3嘉泰姆
   The CXDC65117/CXDC65118 series is a synchronous step-down micro DC/DC converter which integrates anrK3嘉泰姆

 inductor and a control IC in one tiny package (2.0mm×2.5mm, h=1.0mm). An internal coil simplifies therK3嘉泰姆

 circuit and enables minimization of noise and other operational trouble due to the circuit wiring. A widerK3嘉泰姆

 operating voltage range of 2.5V to 5.5V enables support for applications that require an internally fixedrK3嘉泰姆

 output voltage (0.8V to 3.6V). The CXDC65117/CXDC65118 series uses synchronous rectification at an rK3嘉泰姆

operating frequency of 3.0MHz. The CXDC65117/CXDC65118 series uses HiSAT-COT (*) synchronous rectification.rK3嘉泰姆

HiSAT-COT+PWM control (CXDC65117) or HiSAT-COT+automatic PWM/PFM switching control (CXDC65118) can rK3嘉泰姆

be selected.The series have a high speed soft-start as fast as 0.3ms in typical for quick turn-on. With therK3嘉泰姆
built-in UVLO (Under Voltage Lock (Out) function, the internal P-channel driver transistor is forced OFF rK3嘉泰姆

when input voltage becomes 2.0V or lower. When CE=Low,the integrated CL discharge function which rK3嘉泰姆

enables the electric charge at the output capacitor CL to be discharged via the internal discharge switchrK3嘉泰姆

 located between the LX and VSS pins. The power consumption will be less than 1.0μA.rK3嘉泰姆
