XCL221 Datasheet - Torex Semiconductor

XCL221 0.5A Inductor Built-in Step-Down Converters

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. A wid.
