Design considerations for PoE
by Rich Fry, Director ICT, TDK Corporation of America The adoption of Power over Ethernet (PoE) in various applications is growing significantly, largely due to the added benefit it can provide for both the designer and end users: Fewer cords at workstations lower labor costs, and the ability to run an Ethernet LAN cable that […]
Compact dual inductors feature high saturation current
TDK Corporation has extended its range of dual inductors to include the new EPCOS series B82477D6. The seven series types cover an inductance range from 2 x 3.9 µH to 2 x 47 µH and are designed for maximum rated currents from 2.83 A to 7.05 A. A special feature of the inductors, which are […]
Space-saving thick-film resistors span 1 ohm to 20M ohm
Bourns, Inc. announced the availability of a new AEC-Q200 compliant series of thick film chip resistors. Bourns continues to take a leading role in introducing space-saving resistor products by offering its latest Model CRxxxxA series in eight compact form factors — from small 0201 (0603 Metric) up to 2512 (6431 Metric).

SMT interference-suppression choke targets dc-dc converter apps
Würth Elektronik complements its AEC-Q200 product group of qualified radio interference suppression chokes with an SMT-mountable model: WE-RCIS. The rod core choke, available in four versions, is characterized by its high current-carrying capacity and very high saturation power. WE-RCIS is suitable for integrated DC/DC converters, for low-consumption use and energy harvesting solutions, embedded systems, portable […]
Ultra-small power MOSFET gate drivers cut parasitic inductance problems
Each time a power MOSFET is being turned on or off in a SMPS, parasitic inductances produce ground-shifts that may cause false triggering of the gate-driver IC. Infineon Technologies AG adds a device to its cost-effective and compact-size EiceDRIVER 1EDN TDI (truly differential inputs) 1-channel gate-driver family to prevent such consequences. The new device (1EDN7550U) is […]
Comparing magnetic cores for power inductors
It is helpful to know how the material properties and geometries of magnetic cores affect the ability of inductors to store energy or filter current. There can be a mystique surrounding the specs of magnetic cores used in power inductors, due partly to the fact that magnetic materials may not be well characterized for handling […]
4-channel LED driver ICs with built-in MOSFETs target automotive uses
Rohm recently announced the availability of 4ch linear LED driver ICs with built-in MOSFET ideal for LED rear lamps (turn/stop), fog lamps and turn signals for automotive use. In recent years the adoption of automotive-grade LED lamps is advancing from the viewpoint of power savings and design flexibility, while the number of lamps and brightness […]
