Molex Intros PoE Plus Single-Port Connector with Integrated Power Device Controller Circuitry
Molex Incorporated recently launched its next-generation PoE plus magnetic PDJack™ connectors. In developing the PDJack connector, Molex partnered with Microsemi Corp. and used their PD controller PD70200, which meets all power device standards including detection, classification, integrated isolation switch with inrush current limiter and over-current protection, and two events classifications for PoE plus power.

The single-port controller integrates power device controller circuitry and PoE functionality in a single solution for up to 75 percent space savings on a PCB compared to discrete solutions. The new integrated power device jack combines PoE plus power device controller and bridge rectifiers with gigabit magnetics in a drop-in single port connector solution, the new PDJack connector supports functions of all PoE PSE type as required for IEEE802.3at compliance, interoperability, thermal management and EMI standards.
“Based on the RJ45 connector, the fully compliant PDJack connector eliminates complex design and testing for lower direct costs and faster time-to-market,” states Diarmuid Cullinan, integrated products division manager, Molex. “The PDJack connector with integrated power device controller circuitry plus Ethernet connectivity simplifies installation and the PoE plus infrastructure of networking devices.”

A fully-shielded connector with integrated electro-static discharge protection, the robust PDJack connector design is suitable for a wide operating range and passive airflow environments. Available in Class 0, 1, 2, 3 and 4 for optimal power design, the PDJack connector supply up to 25.5W power at 37V to 57V. Two pins output power and standard signal pins provide Ethernet connectivity, with additional pins allowing power-up of external DC to DC converter. The PDJack manages all the communications with the switch/router PoE controllers to negotiate power requirements and manage safe power-up and power down of IP devices, wireless access points, control panels, vision systems and POS units.

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.
