Over the years, a number of methods have been proposed to realize fractional-N frequency synthesis that are based on the basic concepts of traditional integer-N synthesis [1,5]. Among these methods, three techniques are best known in the industry: fractional divider-based, current injection-based, and ∆Σ modulator-based...

This article examines how to synchronize multiple DC/DC buck regulators in a Master/Slave configuration using phase shift time delay. Phase shifting multiple converters prevents ON time overlapping and reduces RMS current, ripple and input capacitor requirements, which will improve system EMI and power efficiency. This...

Most NAND Flash based 2.5” SSDs have RAM caches for high IOPS, the contents of which take multiple write cycles (written to flash) to store safely. One of the disadvantages of this scheme is that the extra RAM memory and supercaps add to the physical space, cost and unreliability of the product (compared to Swissbit...

To ensure the stability of voltage regulators and switchedmode power supplies, the control loop behavior must be measured and characterized. A well compensating voltage controller enables stable output voltages and reduces the influence of load changes and supply voltage variations. The quality of this control circuit...

Ironless rotor DC motors present characteristics highly desirable for speed and position servos. Due to the absence of iron there is no cogging, and the rotor has no preferred positions, phenomena which tend to deteriorate precision of a servo. Furthermore, their low rotor inertia improves the dynamics of the entire drive...

Even though the eGaN FET was designed and optimized as a power-switching device, it also exhibits good RF characteristics. The smallest 200 V eGaN FET, EPC2012, was selected for RF evaluation and should be viewed as a starting point from which the RF characteristics of future eGaN FET part numbers can be optimized for...

Why is it that seemingly similar power supplies have significantly different performance and reliability characteristics? The answer may lie in the specification detail that can be missing from some data sheets, available only in the long-form data/application notes or may even be due to “specmanship”.

The goal of any switch within a network is to first transfer data, as directed, between nodes within the system. The second goal is to perform this task with minimal degradation on the network. The PLX series of switches provide efficient operation in any network with minimal loss in performance. The enclosed document...
