Power electronics is a key element in the world of electronic design and engineering and electronic engineers need to have a thorough understanding of this area if they’re going to create successful products.

In this section, New Electronics keeps designers up to date with the latest developments in the power electronics market – everything from DC/DC converters to IGBTs to battery technology. In fact, New Electronics covers any power product that can go on a PCB.

Power mosfet offers low on resistance

Vishay Intertechnology claims its 12-V p-channel TrenchFET Gen III power mosfet has the industry's lowest on resistance for a p-channel device in the thermally enhanced PowerPAK SC-75, which features a 1.6 x 1.6mm footprint area.

'Green' PoE/PoE+ quad PSE controller

Mixed signal IC specialist, Silicon Laboratories has introduced the Si345x family, which it claims is the industry's most integrated, energy efficient quad PoE power sourcing equipment (PSE) controllers.

Integrated converter saves board space, procurement costs

The ISL8201M is a high efficiency, low noise, dc/dc converter supplied in a thermally enhanced qfn package. The part features is a PWM controller capable of switching at 600kHz, power mosfets, an inductor and all the passive components required for a dc/dc power solution.

Step-down dc/dc converter

Linear Technology has announced the "H-grade" version of the LT3680, a 3.5A, 36V step-down switching regulator with Burst Mode operation said to keep quiescent current under 75µA.

Optimising design of dc fans and inverters

A range of four H-bridge mosfet packages from Diodes Incorporated has been designed to simplify dc fan and ccfl inverter circuits, by reducing both component count and pcb size in space constrained applications.

Built in surge protection

Two families of AC power switches from STMicroelectronics, are said to to simplify the design of domestic appliances and industrial equipment by integrating surge protection that meets the international standard IEC 61000-4-5, which is usually implemented using external components.
