Torex debuts 1.5A step-down micro DC/DC converter

Keywords:Torex? converters? integrated coil?

Torex Semiconductor has developed a series of step-down "micro DC/DC" converters with integrated coil. The XCL213/XCL214 series is an ultra-small (external dimensions: 2.5x3.2x1.0mm) step-down micro DC/DC converter with integrated coil comes with 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 minimise 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 2.0per cent) in steps of 0.05V. The switching frequency is 3.0MHz (accuracy 15per cent), 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 and are ideal for portable devices and digital devices that have a DDR or CPU memory that requires a fast transient response. It is an environment-friendly product that complies with the EU RoHS Directive and is Pb-free.

More details about the XCL213/XCL214 can be found here.
