The XCL206 series is a synchronous step-down DC/DC converter which integrates an inductor and a
control IC in one tiny package (2.5mm×2.0mm, H=1.0mm). A stable power supply with an output current of
600mA 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 3.0MHz, and includes 0.42ΩP-channel driver transistor
and 0.52ΩN-channel switching transistor. The XCL206 series has automatic PWM/PFM switching control,
allowing fast response, low ripple and high efficiency over the full range of loads (from light load to heavy
load). During stand-by, the device is shutdown to reduce current consumption to as low as 1.0μA or less.
With the built-in UVLO (Under Voltage Lock Out) function, the internal driver transistor is forced OFF when
input voltage becomes 1.4Vor lower. XCL206B series provide short-time turn-on by the soft start function
internally set in 0.25ms (TYP). XCL206B integrate CL auto discharge function which enables the electric
charge stored at the output capacitor CL to be discharged via the internal auto-discharge switch located
between the LX and VSS pins. When the devices enter stand-by mode, output voltage quickly returns to the
