XCL102/XCL103 Series ETR28011-004a Inductor Built-in Step-up micro DC/DC Converter (micro DC/DC) Green Operation Compatible GENERAL DESCRIPTION The XCL102/XCL103 series is a synchronous step-up micro DC/DC converter which integrates an inductor and a control IC in one tiny package (2.0mm2.5mm, 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 0.65V to 6.0V enables support for applications that require an internally fixed output voltage (2.2V to 5.5V). PWM control (XCL102) or automatic PWM/PFM switching control (XCL103) can be selected. During the devices enter stand-by mode, XCL102D/XCL103D types prevent the application malfunction by CL Discharge Function which can quickly discharge the electric charge at the output capacitor (CL). XCL102/XCL103E types is able to drive Real Time Clock etc. APPLICATIONS FEATURES Portable equipment Input Voltage Range : operating hold voltage 0.65V ~ 6.0V : Start-up voltage 0.9V ~ 6.0V Beauty & health equipment Fixed Output Voltage : 2.2V ~ 5.5V (0.1V increments) Wearable devices Oscillation Frequency : 3.0MHz (20%) Game & Hobby Input Current : 0.8A PC Peripherals Output Current : 500mA V =5.0V, V =3.3V (TYP.)
