The recently formed Architects of Modern Power (AMP) consortium announced its first digital power standards at Electronica. The consortium, whose goal is to establish "common mechanical and electrical specifications for the development of advanced power conversion technology for distributed power systems" unveiled two sets of initial standards at the conference:
- The microAMP and megaAMP digital point-of-load (POL) specifications define requirements for supplies rated at 20-25 A and 40-50 A, respectively, in vertical and horizontal configurations.
- The ABC-ebAMP and ABC-qbAMP bus converter standards detail mechanical footprints, features, and configuration files for 58.42 x 22.66mm, 264-300W advanced bus bricks and 58.42 x 36.83mm, 420-468W quarter-bricks, respectively.
Products meeting these standards are available from consortium members, including CUI, Ericsson, and Murata. (See: Power Week: Digital Power Consortium Aims for a Complete Power Ecosystem.)

In other product news this week, Power Integrations launched a family of switcher ICs that combines primary, secondary, and feedback circuits in a single package. Offering constant voltage and constant current up to 25 W, the InnoSwitch family includes the primary FET, the primary-side controller, a secondary-side controller for synchronous rectification, and the company's FluxLink technology, which eliminates the need for an optocoupler.
ON Semiconductor announced LED control chips for automotive lighting at Electronica. The NCV78763 smart power ballast and dual-channel LED driver can drive two strings of LEDs up to 60 V. The NCV7691 current controller is capable -- with external bipolar transistors -- of regulating the LED driver current with up to eight LED strings being driven concurrently.
Toshiba Electronics introduced an 800V power MOSFET based on the company's high-voltage DTMOS IV super junction technology. The TK17A80W has a typical CISS of 1450 pF (VDS=300V, f=100kHz) and maximum ratings of 800 VDSS, ±30 VGSS, 17 A ID, and 0.3 Ω RDS(ON).
Micrel has introduced 2MHz boost converters suited for single lithium cell operation and powering applications such as USB OTG and HDMI hosts, tablets, and smartphones. Available in a 2 x 2mm thin DFN package, the MIC2875 and MIC2876 can deliver up to 2 A with a minimum of three small external components.
International Rectifier introduced a new-generation IGBT technology platform. The TO-247-packaged Generation 8 (Gen8) 1,200V IGBTs are available with current ratings from 8 A up to 60 A with a typical VCE(ON) of 1.7 V and short-circuit rating of 10 µs. The company also added nine 75V surface-mount devices to its StrongIRFET portfolio of power MOSFETs to address a wide variety of industrial applications.
Telecom brick converters announced by Artesyn Embedded Technologies supply up to 75 W. The eighth-brick AVO75 series provide a single adjustable output between 1.2 V and 12 V at up to 25 A from a 2:1 input range of 36-75 V.
Keysight Technologies has introduced a prewired power rack for high-power DC applications for applications requiring up to 90 kW. The N8900 Series Rack System allows users to install up to six 15kW N8900 Series autoranging DC power supplies in a parallel configuration that can deliver voltage and current combinations from 80 V to 1,500 V and from 60 A to 3,060 A.
Finally, a new source measurement unit from Keithley is suited for high-power, high-precision I-V characterization of materials and power semiconductors. Featuring a touchscreen GUI, the Model 2460 sources up to 105 V, 7 A DC/7 A pulse, 100 W maximum, and features 0.012% basic measure accuracy with 6 1/2-digit resolution.
