TOREX XCL210C331GR-G

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. Circuits are shutdown to reduce current consumption to as low as 0.1μA. 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 detect 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.
