"micro DC/DC" XCL Series

"micro DC/DC" The XCL series is ultra small DC/DC converters that integrate a coil and a control IC using Torex's unique technology. Our unbending dedication as a power IC manufacturer has maximized DC/DC converter performance, and we have realized a product that simultaneously achieves space-saving, high efficiency, low noise, high heat dissipation, and low cost.

"micro DC/DC" XCL series package type

Saving of mounting space and high efficiency go without saying in the "micro DC/DC" XCL series, and three types are available to meet your needs: an ultra-small "pocket type" with low EMI noise that supports currents up to 1A, a "stack type" that simplifies the manufacturing line to achieve low cost, and a "multiple type" that incorporates a large coil and supports large currents.
A variety of package options enables incorporation of a coil that best matches the control IC, and the result is a "micro DC/DC" XCL series lineup that can be used in a wide range of environments.

Noise is held to a minimum

Wireless and GPS functions are being added to a wide variety of devices, and radio-frequency interference and noise have become key concerns in electrical circuit design. DC/DC converters are sources of noise in particular, and if the quality of the circuit design and board layout is not sufficient, circuit malfunctioning and noise may result. The electrical circuitry of Torex's "micro DC/DC" XCL series is optimized, and this makes it possible to achieve a lower noise than with a discrete DC/DC converter configuration.*(Under development)

Optimization of structure solves heat problems.

Improving power conversion efficiency is a key point in miniaturizing a power circuit. When semiconductor and electronic components are made smaller, the resistance component increases and the loss appears as heat generation. Heat generation leads to impaired component performance and lower reliability of the overall device set. Because Torex's "micro DC/DC" XCL series reduces the loss of efficiency that accompanies miniaturization, optimization of the power circuit from component selection to the heat dissipation structure realizes a small, high-efficiency DC/DC converter.
