DC/DC converter module supplies RF power amplifiers
Designed to supply the voltage to power transistors that are used in integrated Radio-Frequency Power Amplifier (RFPA) applications, Ericsson has launched a 200W DC/DC converter module in an eighth-brick format. The PKB4216C series module offers flexibility with its adjustable output voltage of 15-33V, which makes it possible to power a wide range of power transistors.
Yole explores the power electronics industry
According to Yole Développement, Wide Band Gap (WBG) technologies are almost ready to be used by power electronics integrators. The question is how? Industry players have identified many module packaging challenges. Yole has analysed their insights, and is now presenting an overview of the issues.
Multi-level cell technology is making Flash memory even more prolific
The use of Flash memory is ubiquitous, but the introduction of multi-level cell technology could make it even more prolific. By Ethan Chen & Precyan Lee, Advantech.
Nanowire provides 'ultimate' semi-to-superconductor contact
Researchers at the University of Copenhagen's Niels Bohr Institute are behind the discovery of a new type of ‘nanowire’ crystal that fuses semiconducting and metallic materials on the atomic scale. The breakthrough has great potential, and could lay the foundation for future semiconducting electronics, potentially enabling technologiessuch as quantum computation and solar cells.
Ecomal deal steps up Gan Systems sales effort
GaN Systems is stepping up its sales effort in Europe. It has signed a distribution agreement with Ecomal Europe to promote and distribute its gallium nitride (GaN) high power switching transistors. The partnership is seen as synergistic by both GaN Systems and Ecomal Europe, as many of GaN Systems’ prospective customers in the region already have a relationship with Ecomal Europe.
Fan driver IC offers leading acoustic noise levels
Expanding the company’s portfolio of All-in-One single coil fan drivers, Melexis has introduced a 600mA single coil fan driver IC targeting energy efficient cooling system designs. The MLX90297 incorporates a minimum speed setting and a speed curve which can be tuned through inclusion of just one additional resistor.
Low power MCUs target wearable applications
A family of 32-bit ARM Cortex-M4F MCUs, which are particularly suitable for wearable applications, has been released by Ambiq Micro. According to the company, it’s featured Subthreshold Power Optimized Technology (SPOT) platform allows the Apollo MCUs to consume five to ten times less energy than competing MCUs.
Brushless DC motor animation
This animation shows the correct sequence for commutating a three phase brushless DC motor containing four rotor poles and six stator poles.
Small-signal MOSFETs save space for wearables
Diodes Incorporated has introduced three small-signal MOSFETs in a tiny DFN0606 package, measuring only 0.6x0.6mm. The 20 and 30V N-channel and 30V P-channel transistors require 40% less board space than the commonly used DFN1006 (aka SOT883) packaged MOSFETs, making them suited for next-gen wearables, tablets and smartphones.
SRAM devices suppress soft error occurrences
SRAM memory devices, which have a density of 8Mb, have been released by Renesas Electronics Europe. Expanding the company’s RMLV0816B and RMLV0808B series of Advanced Low-Power SRAM (Advanced LP SRAM), the devices utilise a fine fabrication process technology with a circuit linewidth of 110nm.
