XCL222 - 0.5A Inductor Built-in Step-Down Converters

Download the XCL222 datasheet PDF. This datasheet also covers the XCL221 variant, as both devices belong to the same 0.5a inductor built-in step-down converters family and are provided as variant models within a single manufacturer datasheet.

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.

XCL221/XCL222 Series ETR28008-002a HiSAT-COT ® Control 0.5A Inductor Built-in Step-Down “micro DC/DC” Converters ☆Green Operation Compatible ■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. A wide operating voltage range of 2.5V to 5.5V enables support for applications that require an internally fixed output voltage (0.8V to 3.6V). The XCL221/XCL222 series uses synchronous rectification at an operating frequency of 1.2MHz. The XCL221/XCL222 series uses HiSAT-COT (*) synchronous rectification.
