TOREX SEMICONDUCTOR LTD. (Tokyo Japan: President, Tomoyuki Fujisaka) has developed the XCL213/XCL214 series of step-down "micro DC/DC" converters with integrated coil.

The XCL213/XCL214 series is a new series of ultra-small (external dimensions: 2.5mm x 3.2mm x 1.0mm) step-down micro DC/DC converters with integrated coil that achieve a level of miniaturization and profile reduction that we believe puts these converters in the world's smallest class (*1) for a load current of 1.5A. These converters help save board mounting area and reduce development time because a power circuit can be created by simply adding two ceramic capacitors as external components. The built-in coil simplifies the board layout, making it possible to minimize unwanted radiation noise and operational trouble.  
The operating voltage range is 2.7V to 5.5V, and the output voltage is selectable from 0.8 to 3.6V (accuracy ±2.0%) in steps of 0.05V. The switching frequency is 3.0MHz (accuracy ±15%), and PWM control (XCL213) or PWM/PFM auto switching control (XCL214) can be selected based on the control method.  
The XCL213/XCL214 series use HiSAT-COT (*2) and are ideal for portable devices and digital devices that have a DDR or CPU memory that requires a fast transient response.  
This series is a sister product of our XCL205/XCL206/XCL207 series, XCL201/XCL202 series, and XCL208/XCL209 series. This series is an environment-friendly product that complies with the EU RoHS Directive and is Pb-free.
