目录 1.产品概述 2.产品特点 一,产品概述(General Description) inductor and a control IC in one tiny package (2.0mm×2.5mm, h=1.0mm). An internal coil simplifies the circuit and enables minimization of noise and other operational trouble due to the circuit wiring. A wide operating voltage range of 2.5V to 5.5V enables support for applications that require an internally fixed output voltage (0.8V to 3.6V). The CXDC65117/CXDC65118 series uses synchronous rectification at an operating frequency of 3.0MHz. The CXDC65117/CXDC65118 series uses HiSAT-COT (*) synchronous rectification. HiSAT-COT+PWM control (CXDC65117) or HiSAT-COT+automatic PWM/PFM switching control (CXDC65118) can be selected.The series have a high speed soft-start as fast as 0.3ms in typical for quick turn-on. With the when input voltage becomes 2.0V or lower. When CE=Low,the integrated CL discharge function which enables the electric charge at the output capacitor CL to be discharged via the internal discharge switch located between the LX and VSS pins. The power consumption will be less than 1.0μA.
