XCL102

XCL102/XCL103 Series Inductor Built-in Step-up “micro DC/DC” Converter (micro DC/DC) ETR28011-005a ☆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 (2.0mm×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 0.65V 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 ● Portable equipment ● Beauty & health equipment ● Wearable devices ● Game & Hobby ● PC Peripherals ● Devices with 1~3 Alkaline, 1~3 Nickel Hydride, 1 Lithium and 1 Li-ion ■FEATURES Input Voltage Range Fixed Output Voltage Oscillation Frequency Input Current Output Current Control Mode Selection Load Transient Response Protection Circuits Functions Output Capacitor Operating Ambient Temperature Package Environmentally Friendly : operating hold voltage ...
