General Description
The XCL221/XCL222 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.
