XCL210 Series
ETR28009-001a
50mA/200mA Inductor Built-in Step-Down “micro DC/DC” Converters
☆GreenOperationCompatible
■GENERAL DESCRIPTION
The XCL210 series is a synchronous step-down micro DC/DC converter which integrates an inductor and a control IC in one
tiny package (2.0mm×2.5mm, h=1.0mm). 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 2.0V to 6.0V enables support for applications
that require an internally fixed output voltage from 1.0V to 4.0V in increments of 0.05V.
During stand-by, all circuits are shutdown to reduce currentconsumption to as low as 0.1μA or less.
With the built-in UVLO (Under Voltage Lock Out) function, the internal P-channel MOS driver transistor is forced OFF when
input voltage becomes UVLO ditect Voltage or lower.
The XCL210 integrate CL discharge function which enables the electric charge at the output capacitor CL to be discharged via
the internal discharge 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.

(*1) VOUT(T)=Nominal Output Voltage
(*2) VOUT(E)=Effective Output Voltage
The actual output voltage value VOUT(E) is the PFM comparator threshold voltage in the IC.
Therefore, the DC/DC circuit output voltage, including the peripheral components, is boosted by the ripple voltage average value.
Please refer to the characteristic example.
(*3) Not applicable to the products with VOUT(T) < 2.15V since it is out of operational volatge range.
(*4) EFFI=[{ (Output Voltage)×(Output Current)] / [(Input Voltage)×(Input Current)}]×100
(*5) LX SW “Pch” ON resistance = (VIN – VLX pin measurement voltage) / 100mA
