New Multi Chip Module (MCM)

Combining 2 x XC9235/36 synchronous step-down DC/DC converters in one ultra small USP-12B01 package (2.8 x 2.3 x 0.6mm), this new multi chip module IC from Torex is an ideal space saving solution for applications that need a compact and efficient power management solution for powering both the I/O & core voltage rails of the boards CPU.

The XCM517 has an operating voltage range of 2.7V~6.0V and switching frequency can be selected from 1.2MHz and 3MHz. Control can be either PWM or PWM/PFM automatic switching. The XCM517 provides ultra low ripple performance (<10mV) across the full load range. Available now !

New DC/DC Converter Study Guide

Ever wondered how coil selection affects efficiency or ripple voltage when designing with DC/DC converters ? Equally, the choice of MOSFET can also impact upon efficiency if working with a controller design as indicated in the graph below which is part of the guide (see page 10) and which compares efficiency of different MOSFETs when used with Torex's step-down XC9220 series when stepping down from 12V to 5V.

With this new guide, you have a fantastic tool to complement
your DC/DC design work or simply to brush up on your understanding of the different aspects of the DC/DC and how the different external components relate to performance. The guide is a mixture of graphics and text brought together in an easily understandable way.
