World’s Smallest Class! Ultra‐small, ultra‐low profile package (2.25 × 1.5, h=0.75mm MAX) 0.4A / 0.7A step‐down “micro DC/DC” converters with integrated coil

28 NOVEMBER 2017

Ideal for portable devices, tablets, and optical devices!

Torex Semiconductor Ltd. (Tokyo Japan: President, Koji Shibamiya, 6616: 2nd section at Tokyo Stock Exchange) has launched mass production of the XCL223/224 Synchronous Buck “micro DC/DC” Converter with integrated coil. Minimum operating voltage is 2.5V & maximum operating temperature is 105°C The XCL223/XCL224 series are ultra‐small (external dimensions: 2.25mm × 1.5mm × h0.75mm) step‐down micro DC/DC converters with an integrated coil and control IC. These converters achieve the world’s smallest class of miniaturization and height reduction among output types with an output current of 0.4A / 0.7A.
A power circuit can be created by simply adding two ceramic capacitors, contributing to conservation of board space and shortening of development time. In addition, an internal coil simplifies the board layout and makes it possible to minimize unwanted radiation noise and circuit operation trouble.
The operating voltage range is 2.5V to 5.5V, and 0.8 to 3.6V can be selected for the output voltage in steps of 0.05V (accuracy ±2.0%). The switching frequency is 3.0MHz, and either PWM control (XCL223) or PWM/PFM auto switching control (XCL224) can be selected for the control method. An ambient operating temperature from ‐40°C up to +105°C can be supported.
The XCL223/XCL224 series uses HiSAT‐COT(*1), and is ideal for optical cables that are required to have a fast transient response, small PC peripheral devices, and portable or digital devices that incorporate a CPU. With the addition of these products to our lineup, you can freely select as needed for your application. Torex will continue to expand the XCL series of “micro DC/DC” converters to meet market needs.
