GENERAL DESCRIPTION
The XCL201/XCL201 series is a synchronous step-down micro DC/DC converter which integrates an inductor and a control IC in one tiny package (2.5mm×2.0mm, h=1.04mm). A stable power supply with an output current of 400mA is configured using only two capacitors connected externally. Operating voltage range is from 2.0V to 6.0V. Output voltage is internally set in a range from 0.8V to 4.0V in increments of 0.05V. The device is operated by 1.2MHz, and includes 0.42Ω P-channel driver transistor and 0.52Ω N-channel switching transistor. As for operation mode, During stand-by, the device is shutdown to reduce current consumption to as low as 1.0μA or less. The series integrate CL auto discharge function which enables the electric charge stored at the output capacitor CL to be discharged via the internal autodischarge switch located between the LX and VSS pins. When the devices enter stand-by mode, output voltage quickly returns to the VSS level as a result of this function.
