Texas Instruments Claims Smallest 2.5-A Power Module
TI introduced a new power module with 65-V transient protection that integrates a DC/DC converter, inductor and passives in a very small, easy-to-use package. The 2.5-A TPS84250 meets the EN55022 Class B electromagnetic emissions standard and features frequency synchronization to cleanly power noise-sensitive analog circuits in test and measurement, industrial motor control, medical and imaging applications.

The TPS84250 step-down power module supports input voltages from 7 V to 50 V and provides a positive output voltage from 2.5 V to 15 V in a small, thin 9-mm by 11-mm package.
For applications that require a negative output voltage, TI offers the TPS84259 4.5-V to 40-V input, up to 15-W power module with frequency synchronization and low electromagnetic interference (EMI). This new power module provides output voltage down to -17 V for powering sensors, bipolar amplifiers, split-rail data converters and other analog circuits. For clean, low-noise voltage rails, the TPS84250 and TPS84259 modules can be paired with wide-input voltage linear regulators such as the 1-A, 36-V TPS7A4700 and 1-A, -36-V TPS7A3301.

The TPS84250 and TPS84259 join TI's TPS84k power module family, which also provide power for DSPs and FPGAs that require lower input voltages. TI offers a variety of tools and support to speed design, including circuit topology calculators for the TPS84250 and TPS84259.
Key features and benefits
Opinion: Maximising Synergies between Power Electronics and ICT for improving Energy Efficiency
* 65-V transient protection eliminates additional system protection components.
* Frequency synchronization reduces noise.
* Compliant to EN55022 Class B electromagnetic emissions standard for low EMI noise.
* Very small, low-profile 9-mm by 11-mm by 2.8-mm QFN package is 75-percent smaller in area than open-frame power modules.
Availability, packaging and pricing
The TPS84250 and TPS84259 power modules are available in volume now from TI and its authorized distributors. They are offered in a 41-lead QFN package and are priced at US$5.25 and US$6.00, respectively, in 1,000-unit quantities.

Energy Efficiency with Class D Amplifier Modules
Class-D switching amplifiers are helping audio designers create personal multimedia devices and home audio/visual systems that demonstrate how compact and stylish equipment can also deliver high sound quality and high audio output power. The key to this breakthrough, providing freedom from the large and bulky boxes housing traditional audio products, lies in the class-D amplifier’s high energy efficiency, which is typically around 90%. This allows designers to reduce or eliminate heatsinks as well as using smaller-sized PCBs and smaller components such as transformers, connectors and power supplies.

The Role of Hall Effect Sensors in Power Distribution Infrastructure
Power distribution units (PDUs) form an essential part of modern computing and data communications hardware. They provide multiple outputs for transferring electrical power with maximum efficiency, controlling the power capacity and safeguarding against the possible causes of supply interruption. With an ever increasing need from tech savvy consumers for higher data throughput and greater quantities of data storage capacity, as well as tough international legislation now governing CO&sub2; emissions, the demands being placed on these units are proving challenging for engineering teams to satisfy.
