World’s Smallest Class ! Ultra-small, ultra-low profile package (h=0.75mm MAX) 0.4A / 0.7A step-down “micro DC/DC” converters XCL223/XCL224 Series

Nov 28, 2017

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 x 1.5mm x 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.


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℃ up to +105℃ 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.


(*1) HiSAT-COT is an original Torex term for High Speed Transient Response.
