目录7.相关产品 产品概述 返回TOP CXDC65103系列是一种线圈与控制IC一体化的超小型（2.5mm×2.0mm、h=1.0mm）的升压微型DC/DC转换器。通过在电路中采用同步整流方式，无需二极管，外部零件只需两个陶瓷电容，就能组成高效的升压电源电路。电路因外部零件减少而被简化，可将因基板设计导致的噪音和工作故障控制在最小限度。输入电压范围为0.65V～6.0V，输出电压范围为2.2V～5.5V（精度±2.0％），可以0.1V步进进行设置。控制方式准备了PWM固定控制和PWM/PFM转换（自动切换工作模式）控制类型。CXDC65103系列通过PWM固定控制可控制输出纹波。此外，CXDC65103D类型通过CL放电功能，将在待机模式时快速降低输出电压，并防止输出设备的误动作。CXDC65103E类型通过旁路开关功能，将导通输入和输出，可驱动RTC等。 The CXDC65103/CXDC65104 series is a synchronous step-up micro DC/DC converter which integrates an inductor and a control IC in one tiny package (2.0mm×2.5mm, h=1.0mm). A stable step-up power supply is configured using only two capacitors connected externally. 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 0.9V to 6.0V enables support for applications that require an internally fixed output voltage (2.2V to 5.5V). PWM control (CXDC65103) or automatic PWM/PFM switching control (CXDC65104) can be selected. During the devices enter stand-by mode, CXDC65103D/CXDC65104D types prevent the application malfunction by CL Discharge Function which can quickly discharge the electric charge at the output capacitor (CL). CXDC65103/CXDC65104E types is able to drive Real Time Clock etc. 产品特点 返回TOP Input Voltage Range : 0.9V～6.0V (Absolute Max.
