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.
