Torex Semiconductor XCL micro DC/DC Converters

Torex XCL micro DC/DC Converters combine an inductor and a control IC in an ultra-small package. The XCL micro DC/DC converters are an ideal choice for noise-sensitive environments. Designed for use with ceramic capacitors at an appropriate switching speed, the devices deliver a stable power supply with low ripple voltage. Torex XCL micro DC/DC Converters also provide excellent EMI noise protection. The converters are available in three versions. The pocket type supports currents up to 1A, and the inductor covers the DC/DC converter IC in this version, which enables the suppression of externally emitted noise. The stack type helps in reducing costs by simplifying the manufacturing process. The multiple type supports large currents up to 2A.
